Data Billing

The problem stems from increased data usage !!! My request to MTN Started in February 2015 !!! My bill escalated from average R400 Per month to R2000 and ended with R6500 I requesred to be capped on my data account !!! They used all sorts of excuses From Strikes Ect ect ect !!! (sic) In July with a bit of luck the data was capped and data account was normal again !!1 I requested for a CREDIT !!!!! It sounds like a swear word to them !!!! NO action !!!! You used it pay for it !!!!! NOT ON !!! Surely they can look at before and after !!! What gives !!! Plus the fact that i was in hospital and did not even used my data account !!! They can NEVER transfer me to the person i spoke to !!!!!! They keep on passing the buck !!! The latest !!! I must pay then they will look at passing CREDIT !!!! That we know will not happen !!! I am NOT HAPPY plus the fact that i have been with MTN from inception !!!! Surly someone at MTN can assist !!!!! But they keep on hiding behind so called CALL Centers !!HELP !!!!
