From pillar to post

Mtn has no sense of urgency I've been sent from pillar to post I upgraded online and they sent the wrong phone I called to send it back but nobody contacted me until I called the call centre who then said I could return it to the store. Which I did on the same day when I got to the shop Ndivhuwo the guy that helped me was shouting that "we like ordering online then when things go bad we run to them to fix this was on the 24/06/21 he then did the return and said to call the warehouse on Monday or Tuesday to check of they received the phone and they will give us an RMA number so we can cancel the phone . We called on Monday and they said no call Thursday or Friday to check if the phone had arrived . I called in and then I spoke to Amahle who said the phone had indeed arrived but I should go back to the store in order for them to give me the RMA number and that this was a CPA case and they cant assist I went the same day at the shop they dont do cancellations or deal with such cases the agent said she will call me and try follow up . Got home called the warehouse and spoke to Andrew who said they still checking the phone at the ware house and we should call the next day in order to get it .I called and spoke to Omphmetse and she said she will send an email to escalate the matter and I should call tomorrow I did that spoke to Andrew again and said to call on Monday in the morning I called and Spoke to Zandiswe and she said to call after 1pm I didn't got Amahle again and still no RMA either Mtn staff dont know all their procedures and keep passing the bug or they just not working .This very frustrating as we told not to go to the shops but use online but when we do we dont get what we want and at the shops they still cant help this unacceptable honestly
