Counteract cancellation wows!!!!

As an ex employee of Telkom and hence now a pensioner, I have had a frustrating time of trying to resolve/finalise the cancellation of two mobile contracts after having the equipment for just 2days. 2days of poor and intermittent service, hence the cancellation of these contracts on 29th March 2018. Phoned the call centre at 081180, each time without results. The only thing is that more and more is being debited off my bank account. The frustration is that one cannot speak directly to the "case centre", no communications are coming from Telkom side, except new case numbers and more invoices, whereby they ha e free reign over my bank account. If one has the audacity to reverse any debits, one is charged a penalty of R202.07 after 10 days. I am presently sooooo frustrated and poorer.
