Faulty phone out of box, did not get a new one.

On Sunday, the 3rd of September I decided to upgrade my contract to a Samsung A5 at Vodashop Clearwater. The gentleman that assisted me did not even open the phone for me and help me to enter the sim card etc. I then got my phone and went home finding out that my sim card does not fit into the phone correctly. I then went back to Vodashop Clearwater and had to get a sim swap which i waited 45 minutes for someone to assist me. They advised that it would take 2 hours to activate it but then on Monday the 4th of September, I phoned customer service and advised it was not activated but then I tried to put my colleagues sim card in my phone and it was not working either so in the end, I had a faulty phone. I then went back to Vodashop Clearwater and asked them to assist me. They took the phone and advised that they could not give me a new one even though it is in the 7 day CPA rule. I was highly disappointed in their service as I should of gotten a new phone. The service I received was poor and unprofessional. I am going to now cancel my upgrade and cancel my contract as well. I have been a valued customer for many years now and I do not appreciate the way that I was treated. Thank you
