48 Days and Counting with no Feedback

I have been trying to get feedback from MTN on why my data disappeared. Used to get 10G since I took out my contract, and then after more than a year, **** gone, I can't get an explanation. When I go into a store 19 Jan (that is online) I get told to phone customer care.

I phoned on 31 Jan - We logged a query with billing, I need to phone back 6 Feb - No feedback from billing, I need to phone back 10 Feb - No feedback from billing, I need to phone back 16 Feb - No feedback from billing, I cant speak to billing directly, also couldn't speak to team leader, but they will phone me back (still waiting) 7 Mar - Can not assist, system is offline 8 Mar - Spoke to Agnus, No feedback from billing, ticket still open, I need to phone back...
