***** by MTN - charging non customers bank details

MTN started charging me for a data account in Oct 2018. I received the invoice for this on my private email account. The invoice clearly states someone else's name and details. I contact MTN and was told i had to prove that I am not this person and this is my bank account and not theirs. So I sent my ID and Account confirmation bank letter. They refused this. I got hold of the actual account holder via Facebook, and she said she had already asked them to fix it. She copied me into the mails she sent the store telling them they made a huge mistake and sent her ID and statement again. They still have her documents from when she opened the account with the correct detail, but refuse to share it with her. We have logged almost 6 customer complaint calls, we have been treated like *********, sent to SAPS to get affidavits to prove our identities, and all because MY+TN staff are *********** and the MTN system does not work. Today i again received the invoices 5 month on after all of this. None of the customer care agents will escalate this and the staff at the store just tell us they cant help. To take someones personal bank account details and use it for your company is *****. MTN is committing *****. MTN has not once called myself or their client to try and fix this, or even apologize. Its sickening. I am a Vodacom client, and even though my data price is higher, i will NEVER use MTN and i will make this clear to every person i come across and have the opportunity to share this with.
