Sold a wrong Cell phone

I went to renew my contract looking for a dual phone. I was given a phone, on my arrival at home when I wanted to insert the second sim the phone is not dual. I went back the next day and this time David Baker took the phone back and up until now I do not have a phone. honestly Cell C service it is really pathetic, they don't value their customers, my other line now is off because I had to change my sim to fit in the new phone and now I don't have a phone.<br> <br> Bad Bad Bad service, the sales person doesn't know whether the phone is dual or not and gives me the wrong one and because of that now I don't have a phone 5 days later.
