MBD attorneys wants to ****** R34k from me via MTN but MTN claims innocence but says they only wanted R4.6k which cannot be proved

on 17 Jul 2019, I suddenly got an MBD attorneys mobile text message saying I need to pay R250 towards my R34k yes R34 000 outstanding balance, immediately to avoid further steps would being taken against me for my outstanding MTN account. Knowing that this could be false because I have a WORK contract mobile handset, I speak to the mobile lady at my place of work who handles our mobile contracts and she makes contact on 25 July 2019, with Ivan Breytenbach at MTN via email inquiring about this "HANDOVER" as my account is debited monthly by MTN and there have NO unsuccessful debit orders. Ivan forwards my statement and confirms my account is up-to-date. I respond via email and enlighten him that MBD attorneys sent me a text message wanting me to make payments. He is confused and "escalates" this issue to Ishfahaan Vithaldas (the MTN Collections Supervisor). meantime i call MBD attorneys trying to get more info on this matter and am told to send through a formal letter of my issue and copy of ID. I do as requested, and attach the up-to-date statement(June's 2019 statement) sent by Ivan at MTN on the 25 July 2019. Ishfahaan discovers that a personal account under my name was opened, and there are 3 numbers(3 contracts) that have never been paid. He presents the numbers and the failed debit orders including the "****" banking accounts for these 3 new contracts/numbers. I point out that they have been successfully debiting my monthly payments, they have ALL my details; why was i not informed THE FIRST TIME there was a "failure/reject" on these contracts so we could have picked this matter up SOONER!!! i see this as ***** on my name! He also discovered that around 8th July 2019, these accounts were turned over to MBD attorneys for the amount of R4600 yes R4.6k. all the while MBD attorneys was included in the email conversation with Ishfahaan Vithaldas (the MTN Collections Supervisor) but remained silent. Ishfahaan asks MBD where they got the R34 000 from? I have made several calls to MBD attorneys and all have been a waste of time as they ask me to mail their '***' mailbox with a signed letter and copy of ID; which I have not received even an acknowledgement of my query just the automated email response. My biggest problem is the blatant disregard and disrespect of silence on my query. Both MTN and MBD attorneys actions are affecting my credit profile NEGATIVELY and they do not seem to be bothered to pay me any attention by answering my question as to WHERE does the R4.6k or R34k amounts come from and WHO opened these PERSONAL accounts as I do not need any other account. I need someone to get back to me and resolve this issue immediately and remove ALL negative entries against my credit profile. I am appareled by the lack of service by both MTN and MBD attorneys.
