MTN DATA *****S

Pay ( on account) for 3 gb data on 8th of March, use 20 mb according to mtn system on 9th data is finished! Not mentioning the previous months 4gb that dissapeared without hardly using any data. ( i have much cheaper and beter internet which i use through wifi at home) Spend hours on phone with operators and achieve nothing. Each operator gives a different story! The last operator blatantly **** to me about how much data i used. Told me i used 3 gb between the 8th and 9th and told me to check their system which i did it showed 20mb. Such poor useless service.
