Billed for a device that i never recieved

I had called the Telkom call center sales department, with the intention of opening a contract for the Huawei B315 router, of which at the time it was going for (R349 X 24months) 20GB + 20GB, but on numerous occasions when i called the call center to check the status of my order i was being told that the mifi router for (99 x 24months) 5GB + 10GB was appearing as an order thats being processed for me. I would again tell the person who was attending me that, the order appearing is not what i had ordered. That same scenario happened for about 2 times and on the 3rd occurrence a mifi router router was delivered to my door step which i didn't even open. I immediately called the Telkom call center sales department informing them that the device delivered was incorrect. A day later, the courier guys that had dropped off the device came and collected it and left me with a wapbill number( ********** 8) saying i should use it as proof that indeed they came and collected it. 3 weeks went by without a word from the people at the call center of Telkom sales I eventually opted to ask my father Mr Mnikathi to take the contract at a Telkom shop in Pinetown (Pinecrest Center) since I am self employed and had no payslip to produce.The contract he took is the R369 X 24 for 40GB + 40GB, In short I'm paying for two contracts and this is the second month i'm paying for a mifi router that isn't even with me. This is really frustrating, please assist. This is the first reference number( AI ********** ) i was given on my last review and promised feedback and i've never been contacted instead i,m being billed. Went to Telkom shop and i was also given a case number there as well still awaiting feedback.( ********** 8)
