I HATE MTN - CANNOT WAIT FOR MY CONTRACT TO END

I took an upgrade with MTN last year and I changed my Usage limit to R160 to accomodate a once off monthly 1GB purchase, MTN went on strike for months and upon their return I logged a complaint with them about my data going off like crazy, an inquiry was logged for them to investigate, as always I NEVER HAD FEEDBACK ON THIS. Then they started crediting me with 4GB data on the 21st of each month with my subscription airtime, at first I thought they were crediting back my data which I had initialy complained about. But to my surprise MTN started billing me like crazy - I called and they advised I had a subscription of 2GB data which I never requested and they logged a billing query which was open for almost a month if not more - it came back and accused me of signing up for recurring 1GB data through USSD (WHICH I NEVER DID) - immediately after that I then received sms saying the data was depleted - then in March again they credited me with 4GB and I called - they still said I have signed up for that damn data and they logged it again - I KNOW SUDDENLY OWE R1128 for stupid data that I do not even need - I have a baby coming in less than a month and really don't need this.
