worst service from Jet incompetant store manager.

I bought a cellphone at Jet Palm Springs mall on the 12th November 2019 using my Jet account.The battery of the phone was so bad that the phone had to be charged 3 to 4 times in a day. I went to the store on the 14th November 2019 for them to change the phone as it was still within 7 days and was faulty. I spoke to Mlungisi the assistant, who could not assist and I asked for the store manager who is Tebogo Tshipenyane. He advised cellphones are no longer exchanged or returned and he advised it`s my problem now, as I am the one who chose the phone. I was in the store for 2 hours, when I initially requested for the manager I was advised he is busy but when I asked for the manager`s name and surname, all of the sudden he was available. The manager was so rude and I asked where in the policy it stated that the phones could not be exchanged or returned and he says its a new policy. I could not believe the incompetence from management level and he was so rude and he didn't care what so ever. I even called the customer experience at EDCON and I was advised to wait In the store someone was going to call that store. I waited nothing happened, after an hour I left .On the next day I called the customer experience again and gave them the query number I received, which is *** when I called initially and now the agent advised their turn around time is 48 working but no one advised that prior. This is the worst service I have received from management level, as the Jet account holder I am dissatisfied and I want this issue resolved. I want to pay off my outstanding balance ,so that I can close this account.I no longer want to deal with such incompetence ever again. I am requesting the head office of jet to contact me , on *** to resolve this matter and I do not want anything to do with their phones and Jet stores as a whole.
