Account no ********** 25

I had a contract with Telkom which ended in Feb 2019,but as from Dec,Jan and Feb i was unable to use the WiFi including data I've logged numerous complaints before the contract ended telling them that it connecting while they are still debiting me every month and they told me they will send a Technician to investigate should it be their fault than they will reimburse me for Dec, Jan and Feb. The Technician only came on the 02/05/2019 to investigate and his findings were it Telkom's Faults and left this ref no ********** his name was Sifiso and stated it does not connect at all the device and the sim card ,he asked if i had cancelled the contract and i said no it was ending in Feb and i was told not cancel as yet because i must wait for the Technician to do the investigation.Telkom continued debiting me while the device was not working/connecting and today they are telling me i owe them R334.64 FOR WHAT? FOR WAITING FOR THE TECHNICIAN THE SAME TECHNICIAN THAT TOLD ME IT'S TELKOM FAULT THEY MUST REIMBURSE ,I asked them to reverse because i cannot be paying for their fault.
