Telkom/Selldirect

I had a upgrade done in December 2018 through Selldirect/Telkom. The contract was for a new ****le 10 GB for R139 a month. Simple as that I thought! They have been deducting unbelievable amounts off my account!R656????? I never signed up for that and I made it very clear on what contract I wanted/was getting into and it was confirmed by the consultant that I would not pay more than that! So ********* you *******s are! I have now resorted to cancelling my debit orders! ***** you!
