MTN are the worst you have to pay for their mistakes

MTN by far the worst when it comes to upgrading online, so i waited for my contract to end before i upgraded in order to avoid early upgrade costs, so i phoned MTN to do an online upgrade and so it begins, i specifically said numerous times not to upgrade the one number and was informed they will upgrade my number what a total waste of time they upgraded the wrong number after it was made clear which number to use, so now this has been going on for 4 weeks i was informed to give the device back that was upgraded on the wrong number in order to do the correct contract i was informed to either go to mall of africa or a courier wil take 7 to 14 days to pick up the device and so i went to mall of africa to return the device, 3 weeks ago then i received an sms stating that the repairs on my new device wil take an x amount of days and so i phone MTN again to ask what needs to be repaired on the brand new device that was returned due to incorrect upgrade and so the nightmare starts everytime i am being transfered to someone else who claims they will phone be back but no one ever phones back, so agter 4 weeks i am at wit end with the lies and bulldust today was the last day of being **** to i phoned this morning 4 times being transfered to departments and so forth then the call either gets cut or you are on hold for hours. so today after i phoned and was informed that the cancellation is stating pending on their system the call magically gets cut off i phone them back right away having to explain my story 1000 times to get to the right department then a lady informs me that the cancelation was done after i was being told earlier that it still states pending i though this is to good to be true. i asked her why i was even being billed double after my contract was done in November already she informed me that i need to pay for cancelation which i feel its not my fault they upgraded the wrong number so why must i pay for their mistake, i went to my nearest MTN store and wanted to give them a last chance to upgrade guess what the system still show pending so now i am being **** to after i said i wil get my lawyers present because this is not my mistake wow MTN what a disappointment this has been i have been a loyal customer for 15 YEARS imagen and this has never happen i ap totally disgusted with the service i have been receiving for the last 4 weeks i will definitely move to another service provider after this!!!!
