MTN ***** Reporting form has not worked for weeks

My accounts were changed by Maverick Telecoms(initially passing off as MTN) WITHOUT MY CONSENT. Weeks after confirming that the accounts would be reverted nothing has been done, countless email and commitments have lead to nothing. That a company can change packages without consent and then not rectify it ridiculous and in my opinion entrapment and simply *******. I logged a call with MTN customer care ref no (***)and no response has been made. I tried to complete the MTN online ***** form but is has been faulty for week.
