After paying for 2 coupons for two massagse and only getting 1 I repeatredly contacted the company { making sure I took screen shots}. They never responded { something I have since found out is typical for them} and I contacted my bank to organize a refund, supplying the screen shots as proof.
Do your homework before dealing with these thieving liars.
AVOID AT ALL COSTS.

I purchased a Kid's Learning Tablet from their website, listed for $24 (discounted from $59, supposedly). They advertised the item as a touch screen learning tablet with heaps of touch screen letters and numbers. The image they supply is of a tablet with what looks like a computer-type touch screen complete with battery signal bar in the top left and clock in the top center. When I received the item, it was no more than a plastic base with a cardboard face designed to look like a tablet. Okay, I was unhappy with the item and felt that it was misrepresented in the description, so I just want to send it back for a refund, and no more problems.
Unfortunately not the case. When I reached out to Living Social, they sent me what appeared to be an automated email stating that in order for them to assist me I would need to login to the website, go to my account page, and confirm that my name was correct. If it was, in fact, correct, I was advised to delete it, and re-list it. I still have no idea why they asked me to do this, but I did it anyway. Fine.
Once I emailed them stating that I had done what they requested, they sent me an email stating that I needed to forward to them photos of the damage to the item. As I described above, the item didn't have any damage, but was falsely advertised. I forwarded screen shots of their own false description.
They promptly got back to me and said that even though the item was not damaged, they still needed photos of the item. So I took the photos they requested and sent them along. That was over 2 weeks ago, and I have not heard from them since. I've sent follow up emails asking for news, to no avail. Their website states that they abide by a Code of Conduct as created by the Australian Direct Marketing Association (ADMA) and the Australian Interactive Media Industry Association (AIMIA). By signing this code they have committed to providing their consumers with clear, accurate and honest communications, among other obligations. They have not lived up to this code, nor are they abiding by the Australian Competitions and Consumer Commission rules stating that businesses are not allowed to make statements that are incorrect or likely to create a false impression.
At this point, I will be reporting them to the ACCC, but don't have very high hopes of receiving any type of response from living social. I would not recommend purchasing from this website.

I have learnt an expensive lesson. Do not dabble in professional services listed by these people.
Bought a voucher for gardening from Diamond building maintenance. The company was very dodgy, kept rescheduling and failed to show up, not once but twice. The director is a very young girl which responds to emails with love hearts and smileys. Alarm bells should have rung but I got sucked in. Further research tells me they only use voucher sites. Not sure if they have a valid abn or are real as such.
Anyway they didn't provide and I lost over a hundred dollars as livingsocial doesn't take any responsibility. In fact this is how they profit. Unused vouchers and dodgy busineses. The customer 'service' was rude and illiterate. Always spoke to a different person and sent a generic email. Had to find them through Facebook to be acknowledged. Stress and anxiety overload as it is very difficult communicating with a party that doesn't care. Went through consumer affairs and they couldn't even get a response. Next step is paying more via VCAT. Ugh...horrendous!!!

Approximate cost: $100
