UNHAPPY DISGUSTED SERVICE

I have purchased a Redmi At Mr Price promenade last year November. I have experience battery charging problems, booked in this unit in Belhar Mr Price, month later received an exact same sealed unit, 2months in having that device same problem persisted rebooked it with the request that I need a credit to exchange it for a different brand and just pay in the difference if I have to but got flat out refused. I am very disturbed and disappointed in the service to how Mr Price and Vodacom Deals with cellphone repairs, I have been back and forth with Mr Price and vodacom with this issue and I'm without a ozone for two weeks I am being given the run around and being offered a sealed unit again! I Don't want a Redmi Again I want a credit because I am very unhappy with this brand . I have been dealing with aneesa at canal walk and all she can say is the best the advance center out in jhb can do is give me a sealed unit! I have also explained to them that I work from my phone and they have the time to give me a back and forth run around just for a credit. This is absolutely unacceptable!
