MTN fraudulent billing

After six months still no joy from MNT. On a fixed cost contract my two accounts jump from R97.99 in Dec 14 - Jan 127.99 feb 127.00 marc 155.99 april 155.99 may 164.43 - Now in June they only remove extra data which was never requested in the first place NO REFUND -- I bet you will not get it right but CELLC is looking good.
