Bad service, not credited with contract amount

Disgusting service, renewed my contract at MTN Eastgate in December. New contract should be 4GB and 200 min per month.

Only received 3.5GB per month. Called at Eastgate on Thursday 6 Feb and an incident was raised - promised an answer on Friday.

No answer Friday, or Saturday - had to go back to Eastgate on Monday 10, STILL NO ANSWER, was told that the incident logged was still open. I was then given a cell number and told to WhatsApp in the afternoon for an answer. (Not phone as ghe do not answer but WhatsApp)

WhatsApp sent on 10 and 11 Feb and STILL NO REPLY!!!!!

worst service I have ever had
