Im being charged for a phone i dont have.

Im now really getting ****ed off with telkom as it seems that they dont know what they are doing. Im actualy regretting not taking the contract with vodacom as i did all this years.<br> I received a samsung s6 edge in november which i send back immediately as i was not happy with the device, i did not even use the device.<br> In december i receved an invoice for R928.00 and i asked the sales agent how i can pay for a device that i dont have as i immediately returned it to telkom, she advice me that she will send back office the request to cancell that invoice. i received another invioce for the s6 edge 64 gb for R890.66 again for a device i dont have. why was this device never cancelled on my name as i never used it as promised by the Sales department. i can only pay for a device that i have and not for something i returned to telkom immediately<br> Can a manger please contact me on 015 290 *** as i now feels like cancelling my contract and returning the new device. I received my device the s6 edge plus 32 Gb arounfd the 23 of december 2015 as is aware of the payment now on 20/01/2015.<br> My bank account was debited today with R890.66 for the s6 edge 64 gb device i dont have
