Where's my data and my credit????!!!!

Dear MTN, you just can't get it right! I've more spent time on the phone to you in the last 5 mths than in the past 10 yrs I have been your client! The real issue, which your call centre agent uncovered on the 18/05 was that the automatic data/SMS/airtime recharge every month was failing. No one picked it up before this. I'd phoned 808 2 times before this & gone to The Glen shop 2 times. All they could tell me was it was my fault my accounts were so high because I was using data for a lot of apps. The call centre agent on the 18/05 said she was going to process a credit for all the amt I paid for each month but not gotten benefit from. This would take 7 working days. She made sure that on that day I got the data/SMS/airtime recharge for May. NOW I find out that I haven't yet got my credit and - guess what? - MY AUTOMATIC RECHARGE OF DATA/SMS/AIRTIME DID NOT HAPPEN TODAY - THE 01/06! At this rate CellC's buy back porting option is looking very attractive. Kindly do the following: 1) Credit me and 2) Make sure I get my data/SMS/Airtime recharged (every month). Not too much to ask is it - especially since I'm paying premium price for it which you debit without fail every month!
