Worst customer experience

Dear PepCell<br> <br> Last week Tuesday, my mom and I went to your store to purchase a phone. After we paid, the terms and conditions was explained to us and Gakhima clearly stated that if there is anything wrong with the phone, we can exchange it within 7 days of purchase. <br> <br> During the week, my Mom had trouble with the phone, it kept going off and she couldn't make calls, the phone does not ring when someone calls her, etc. Yesterday when she took the phone back to the store, Gakhima stated we the phone needs to be sent away for an assessment first. This is not was explained to us. I am utterly disappointed in the service from your store. The money we gave you was not false, and in return, we expect great service!<br> <br> I am requesting a manager to call me and sort this out.
