Contract not cancelled and listed as a default on my ITC

Good day, I took a contract With telkom last year February 2017. When I went to the store, the system showed LTE coverage at my area. So I signed the contract everything got approved and I received the device. Went home and the modem worked but I had no internet, left it on the whole night and nothing worked. The very next day I took it to back to the store, everything as is with the sim card. The manager had a look at it and switched it on. Worked perfectly in the store, he suggested I try changing the cables. Took it back home and tried it again, but still no connection. Took it back the very next day again and asked if I could cancel as there is no network in the area. The manager explained that there is a process and tried to help. He sent another test modem and asked one of the technicians to come check just to make sure before we put the cancellation through. The tech came and confirmed that there is in fact no LTE coverage in the area and the modem will not work. So basically I drive everyday that week back and forth to the telkom shop. Even though it was in the 7 day period they did not want to take back the device of cancel the contract. Which was frustrating because they give you a 7 day period of what?????? I reluctantly agreed to go through the process even though it was within the 7 days period. The manager notified me if i cancel the contract without the technician coming out, i will be liable to pay for the contract upfront.They opened a case to investigate the network in the area then there after they will cancel the contract..... It took literally over 1 month for the tecnician to come and test the network. In this time I wasn't going to pay for a service that I don't have. What's the use? Every time I reversed the debit order I went to the store and asked them to add a note on the system to say that the debit order is reversed. As you know you can never get hold of the telkom accounts department even if you hold on for an hour. The call centre service is ridiculous. The store refused to take back the device during that period. When the technician came out to check, within the same week I took the device back to the store. I asked them to add a note on the case number stating that I will not keep something a device that im not paying for. Note that this was 3-4 months after I took the contract. They handed my account over to the attorneys for not paying, they called and I explained the situation. They said once the contract was confirmed cancelled telkom will get in touch with them. I did not receive any communication there after from them. In june/July I got an sms to say that the contract was cancelled. Not stating if there is an amount outstanding. During this time till now, nothing was sent to say that I have an outstanding amount on my account. I recently app**** for vehicle finance and I got declined because telkom listed me as a default payer, it is still showing on my ITC as owing R3001.00 which I have no idea for what!!!!!! Tried calling the call centre from last week and I never got through. I sent a message to the Facebook and Twitter page. I did receive a response the same day, but they just logged a case and stated that I still have the device. I forwarded all reference numbers and pictures I took at the telkom store for the correspondence that was sent on their system but they their accounts department to confirm with the store that they have received the device, even though I sent a picture of it and it reflects on their system. I am currently sitting in a situation where I can not get finance because telkom has no customer service what so ever and are too *********** to do their work properly. Its already been 1 year and this matter is still not sorted. I have an amount owing on my account which I have no idea what it is for as I did not use the service or have the device. They had 6 months to confirm with the store if they received the device but nothing was done. Why should I suffer because telkom does not have proper information on their system and no customer service.

Can someone please assist with clearing my ITC TODAY as it isn't fair that I get held back because of terrible service on telkoms side.

Sincerely really frustrated and disspointed.
