Wrong product delivered,after complaint no feedbac

I wanted to order a rocking horse, but no EFT's was allowed for it was next day delivery. So I had to get my husband to create an account for himself in order to buy me the rocking horse on his credit card. Next day delivery is only for JHB and not CPT, so I waited patiently since Wednesday for delivery. The rocking horse was delivered today, but was the wrong colour. I phoned groupon, not wanting to hassle my husband with my problem, they refused to help me. After I got my husband to phone groupon and they promised to phone me to arrange the exchange, no phone call received. I had to once again phone groupon to hear what was going on. I needed the horse for tomorrow. Now I have to write a letter to explain what happened with the wrong colour delivered. I am sorry but I refuse to write the letter and I want somebody to contact me ASAP to arrange the exchange to be done tomorrow, Saturday 30/05/2015. It was not my mistake the wrong colour was delivered, the correct coloured was ordered.<br> Thanks<br> Yolandi
