No response during or \after "***** case"""

After applying for a new contract on 16 th of November. I was notified that my call limit had been reached and I was soft locked. Called in and was told that one of my numbers has used R 3500 they gave me the no but it was blocked. Made an affidavit emailed it through. Now to find that there are another 2 lines in my name each running a bill of about R 3500. \Don't worry we won't debit you for these lines as the ***** Department is busy with it."During which time no emails or calls were answered by the \""***** department \"" . 31 of Dec R 11000 debited from my account. Still no communication from \""***** department \"" I'm starting to wonder if mtns ***** department exists. I would love to know how these lines were so easily opened and where is this ***** department. I have been a loyal customer of mtn for 15 years and don't expect to be treated this way. """
