Bad service

In September 2015 I app**** for a contract at Telkom, they told me that I qualify for a Samsung tablet, I declined the tablet and requested. A Huawei cellphone. They approved me for this. In my first installment, they deducted for both the tablet (which was never in my possession) and for the cellphone. I called them regarding this error and they assured me they would send an enquiry to head office for the tablet to be removed and to give me back my money. This never happened! They have been deducting from my account for the past 5 months for a tablet I never took! After countless calls I have made to them, all they have told me is that an enquiry to head office will be sent I must wait for feedback and reimbur*****t but this has never happened! I have had to reverse a couple of these debit orders because it was impacting on my finances, then after this they suspended my phone contract! I do not receive any data anymore for the cellphone contract I agreed to.and they cut off the telkom simcard aswell! All of this has had a negative impact on my credit record and I receive no solution to this matter from Telkom! Instead they have handed the matter to debt collectors!
