Unhappy about phone - Consumer Complaint for PEP STORES

Im really unhappy about the service and terms of this franchise. I wanted a refund because I wanted to exchange it for a more expensive 1 because the 1 my wife bought me as a gift, had signal problems on mtn. Abigail at vangate mall branch was persistent that they cannot assist us, she was the 1 who sold the phone to my wife without even recommending something better, so all she wanted was a sale. Pep cell has the worst customer service as well as t&c's. The phone was bought last week and Wednesday, six days ago from today.
