so tired of the bull****

i have had the most unpleasant experience with MTN for the last couple of months with absolutely no satisfying resolution since September i have had to fight with you people about my contract and how payment has been made i even laid a complaint about one of your consultants about how rude and u unprofessional she was and you just did nothing about it all you told me was we cant find the call on both our system a call that i have on my call logs that lasted more than 17 minutes but somehow you cannot find it such a big organization. Than end of December i specifically told you people that i want to change my payment to cash and not debit because of all the issues where i was paying and getting confirmation of payment and still getting debited and having to pay penalties which were not my fault. on the 18/01/2021 i got sms stating my billing has been changed to cash so on the 25 i payed cash than boom later on in the day i get debited so basically i payed twice in one day and this morning i get sms stating thank you for your payment which was referring to my cash payment so what the hell is going on at MTN is there no one who can get this **** sorted you are causing me anxiety on top of all the stress im going through loosing family members and having family members in hospital for covid you are deliberately making my life a nightmare because you do not value your customers one bit
