***** on my account. Breech of contract

Connected Vodacom fibre over a year ago and have been regretting it from day 1. Took 6 weeks to connect the line. Constantly have my fibre connection interrupted. And now I have had additional lines added to my account without my request, constituting a breech of contract and putting me at severe financial harm. Multiple calls to call centre and emails to ***** dept with no feedback or action.
