Data dispearing

by ariaana-peters 2 I can't explain the frustration I'm having with MTN, I have been a customer of MTN for 8 years and I have 3 contracts with them. Being the unfortunate loyal customer that I am I keep dealing with the service I received from them. I called MTN yesterday the 30th April 2016 asking them to explain to me how I can use 5GB of data in 5days and for 3min on a call spend R5. The lady who was really rude I even told her I'm sorry if it seems like a stupid question, only delt with the data issue advising that it's my data share with another number I own. What puzzled me the most is that I removed my third contract number from data share already and was advised it's still reflecting my fiance also bought data for his number as his data was finished. If the issue was data share which still does not explain 5GB of data in 5days why did he have to buy data if I still had data. MTN please advise how this is possible. This will definitely be my last 3 contracts with MTN if this is MTN 's rates and attitude.
