Frustrated and angry!!!

I bought a WiFi router device on contract with insurance on the device for 24 months . The contract is from June 2016- May 2018. So telkom debit every month the contract fee with the insurance amount together from my bank account. I experience trouble with the device in Oct 2017 so I took in the device because I'm paying insurance on it to be fixed. The consultant I spoke to at Liberty promenade, Mitchell's Plain Telkom shop told me they will take device in and send it for repairs which he did and told me it will be fixed the latest in 6weeks. He also returned back the SIM card that was in the device back to me. He told me they need to send the device to head office in Johannesburg. He packed the device and seal it in front of me ready to be send registered mail to their head office and he gave me a ref no which I can come into the store and check with them how far the fixing process will be. I returned back in around 4weeks back to the store to check how far the device is only to find out its by the insurance company. Another consultant told me to give another 2weeks to come back again. I returned again in two weeks after still to find the device at the insurance company. It went on like tht for a month after they still couldn't sort it out. I got frustrated coz I had to use the SIM card in another phone to receive the data and the phone I use always swith off many occasions. I really got frustrated because Telkom not helping getting back the device. Four months after I gave in the device they told me to call the insurance company. Why do I have call the company out of my pocket if they dealt with it in the first place and which they have to sort out. We already in April and I have receive no feedback yet from Telkom of my device. I think it's pathetic that no one of telkom assist me and tell me to receive my device. After all I'm paying every month insurance on tht device but I don't use it. Can you please help me hello peter.
