No response to customercare queries & #141 continuously experiencing technical dififculties

I am extremely frustrated by poor service at MTN 1. I have sent numerous complaints to the ********** address with no response despite having received Read Receipts 2. The MTN #141 “experience technical difficulties” most of the time – most recently I have been calling every day since 16 March only to receive the automated voice message that I need to try again later 3. I upgraded my MTN package on 1 March 2018. I received notification on 15 March that “you have started incurring cost from your usage limit. To check you balance dial *141*1*7851#” I did so and simply received a message of a Rand amount of cost incurred of my unbilled usage. I called #808 on 16 March to be told I had free minutes still available, but was being charged for calls. The agent could not explain why I was incurring call costs when I had not exhausted my free minutes allocation and escalated the query (Ref 1- ********** 7436) and said I should call back in 24hrs for an answer. I called back on 19 and 20 March to be told this query had not been picked up by anyone to address so no answer yet. The query was re escalated (ref 1- ********** 1105). #141 still not working so I do not know what ismy balance of minutes or Data 4. I was told that i was also being charged for Data as I had exhausted my free data and was now paying for data at the “normal” rate which is much higher than bundle rate. I am most unhappy that at no timer was I notified that I was using out of bundle data (and could not check my balance because #141 is experiencing technical problems) and as a result have incurred unnecessary costs 5. I was told during February I could call the MTN Direct complaints number ********** but tried calling repeatedly but the call was never answered.
