Very bad service from Fibre line dept

I have been battling for the last month for Cell C to update my account payments on my fibre line. I have sent the proof of payment and as promised that the finance dept was going to update the account as they moved over to a new system and the payments was on the old system. To date no feedback.

I escalated the matter to Tankiso the supervisor, he said Sibusiso or Tshegofatso was going to phone me back within 48 hours, that was 3 weeks ago still no feedback. I have been phoning and leaving messages for him he is not phoning me back.

Worst service ever!!!!!!
