MTN Bad Customer service

Hi , trust you are well , please can i get someone from MTN to give me a call that your customer carline as well as your branch in Durban North ( HYPER BY THE SEA) cant assist or fix the problem. i currently have 7 contracts with you , OOP's sorry 6 now because i had to cancel one as it was ending the contract period. No sure where to start but the first problem is that all my contacts are on two debts orders with the same banking details. secondly i pay the account and my son gets all the prompts when there is updates etc. In October he got a prompt to say that a contract is expiring , i then went to Mtn and was told yes and if i did not cancel or upgrade the R299 contact who be automatically become R 1.800 , now you can imagine if i did not get to know about this and the amount goes off making all my other debits that go off at the end of the month sort. I suggested that we upgrade but that even was a total disaster i was told come in later and i can just sign all will be in order , evetime i went in there was an excuse and when i finally come in again nothing was done as they only did the documents them, and then guess what happened only to be told by your mtn employee that someone moved? migrated not(actually sure what happened) and i could not get the upgrade and that's when i decided to cancel as i did not want the 1.800 charge that was two weeks ago . Now this morning i was told they cant check as the guys who assist is off sick , therefore can i ask some one from MTN senior or some one that can just assist give me a call to resolve this problem, My name is Robert and my cell no is ***, kind regards Robert Speranza awaiting your response and call
