CTM ***** from customers

CTM ***** from customers, I bought 2 shower screens from CTM in November and had one returned on the 3rd of December (after basically begging them to collect the screen as I could not use it). I sent my banking details on the 5th of December and have made several phone calls with regard to my refund. I was told on Tuesday that my refund would be processed on Wednesday. I still have not received my refund!!! CTM are *******. I want my money back asap!
