Non functioning call center

Since December 2019 I have been trying to get my contract changed to pre-paid.

Firstly I paid all outstanding amounts to Vodacom. They sent me an sms advising that the account has been changed. When I wanted to do a sim swop to find out that my number has been deleted.

I once again contacted the call center, sending me from pillar to post and no resolution.

3 weeks back I sent a mail rather, hopefully someone on this would be helpful. That was clearly not the case. I was informed to send POP of my account payments, I advised them to listen to the recordings-which they clearly never did, as their agents advised the route I should follow to get my number back

This morning I receive a mail, that I must contact collections-the reason I sent them a mail in first place is that collections asks for my cell number-which is no longer on the system.

Its been years that this call center of Vodacom has been an issue, however now I really believe they have totally lost the plot.

I only want my number back and its taking me 6months thus far to get it.

I wonder if they would wait for 6 months for their account payments....
