We had a number of roller shutters installed on our house a few years ago and are happy with them. However, the company that sold and installed them keep harassing us regularly with phone calls, trying sell us more. We have repeatedly told them we are not interested, please leave us alone and please do not call us. Despite this, they still call and harass us to buy more of their crap on a regular basis. We regret ever buying anything from moderngroup.com.au. They have been nothing but trouble for us. Five years later, they are still hassling us over the phone despite repeated requests to be left alone. Avoid, avoid, avoid.
