Nonauthoriszed *****ulent deductions

I previously took two contract with telkom as an upgrade from my previous contracts. I must say it is disappointing to find yourself as a loyal customer for 6 years to encounter non authorized amounts going off on my account monthly. That each time you make an inquiry with them your told different stories. I have not signed up for any subscriptions yet somehow I'm liable for their system error that keeps adding subscriptions that I don't even use on my account. Every time I'm told your account will be credited, how fair is this to other creditors and me as a loyal paying customer? I have done nothing but honor my side of the contract and how they thank me in return is appalling. You cannot bridge a contract as you like without consent, what happens in the incidence where such extra funds are not available? Will I then be in arrears for what they claim is an automated system error? With the previous contacts I've had I have never encountered such inconsistencies that now it feels like, they have found new ways of de*****ing customers with their unfounded allegations and numerous stories that come up from different stores and consultants. It's like they have run out of excuses to cover up for the current **** nje.
