I app**** online at TELKOM on 21 September 2017 for the online special for 50gb smartbroadband contract which included 100gb day & 100gb night data, wifi router and TV Box for R749.00. On 6 October 2017 the courier services only delivered a sim card. When I contacted Telkom the informed me that I only app**** for the sim card for R749.00. I requested them to cancel the order as this is not what I wanted. On 16 Oct 2017 the courier again delivered a package with sim card, wifi router and extender. I contacted TELKOM again and inquire about this delivery. They indicated that I app**** for a 10gb contract. I indicated that I app**** for the 50gb contract and that I cancelled it, and that I did not ask for the 10 gb contract. I requested them to cancel it and to send someone to collect the wifi router. According to my bill I now have to pay for 10 gb data I did not use in October as well as for November 2017. I am not prepaired to pay for something I did not ask for. I have phoned Telkom several times, I went to the branch and I send e-mails to the Escalation Department on this matter. Without any success or assistance on the side of TELKOM. On 7 Nov 2017 David from Support services contacted me again and I indicated to me that he will deal with my issue. He indicated that he can only cancel the application after receiving the wifi router. On 8 November 2017 the courier services collected the router and I tracked the parcel to Johannesburg and was received. On 15 November 2017 the money for the 10 gig contract was deducted from my account. When will this be removed from my account and when will I receive my payment back? Hope you can assist. I am not willing to pay for services I did not use and did not want.
