My Mum had her back patio painted by iPaint. She asked for a green/grey colour. The colour they put down didn't look green at all. The contractor assured Mum it would turn greener when dry. It hasn't. She emailed them and they've agreed to come fix it, but subsequent emails to arrange a day have resulted in silence. If they return our emails and come fix it I'd rate them higher, but at this stage feeling like the silence is not good customer service, so hence the low rating.
