I am being penalized for ********** activity

3 weeks ago there was ********** activity reported on my account. Someone was allowe to do a SIM swap using my ID details. This person rang up a bill of R93K. Whilst this was happening Vodacom suspended 3 out of the four lines. Yep you guessed it - they suspended all my other lines except the ********** line. They asked me send them an affidavit so say it wasnt me. I did so promptly with a copy of my ID. Only to be phoned a week later to be asked for a copy of my ID and the affidavit. After confirming I did they said they could see it on the system!!!!! They still did not block the line and the guy went on spending merrily. I was then hastily called on Friday 3rd July to be asked (for the first time) to perform a SIM swap so that the ********* can be stopped!! WHAT????? I was then told a credit would be passed for that spend. However until that credit has been passed my line remains locked. It is now 3 weeks in total. ***** dept says they passed the credits. Accounts says they didn't but neither would pick up the phone to find out what the problem is.I have now spoken to 5 different people in 2 days and no one is calling back. This is the worst service ever and I'm closing my accnt
