****** Debited After Cancellation

Telkom is at it again, debiting after cancelation, I have seen many reviews regarding this and now its happening to me, is this coincidence or is it just ignorance in order to ****** money from their customers. I logged a cancelation on the first of June almost an entire month passed before I received a call to acknowledge the cancellation the service agent confirmed that they had received the cancellation and promised to call back within 30mins, that call never came up until today however their accounts department seems to be working perfectly in charging their customers. Surely their systems are all linked with notes and alerts of cancellation. I guess not in Telkoms case. Today I received a call from them regarding upgrades. Never have i ever seen a bunch of ****** and ***** like telkom, social media and bad reviews doesnt affect them at all, no senior managers or persons of responsibility to be found during problems. Their walk in shops are filled with complaining customers but nothing changes. There are many service providers these day do we really need Telkom at all.
