Disgusting service

Purchased a 2 year router contract from the cell C shop in malmesbury during June 2019. The monthly installment is R359. On the same day husband connected the router and immediately experienced that the 5 bar signal on the router indicating the strength of the signal reflected on 2 bars. With the 2 bars the router worked. In the same week this was reported to the shop and the manager mentioned that we are lucky to have a signal. They were aware that the signal in this area was weak. On 1 December we received not signal and the signal bars showed red. On 2nd we tried again and it still showed red. My husband went to the shop on 3 December and reported the problem. One of the salesman told him to move the router and still it was inactive. The next day he went back to to shop and reported that it is still not active and it is very inconvenient. He was then advised that the matter would be reported and a technician would come out and the matter would also be reported to a manager. This never ever happened. We again went to the shop and were advised to return the router and on 27/12 we did this and the cancelation request was signed by me with the effective date being 02/12. A full payment of R668 was deducted. This was for the router and a cellphone contract which was signed +- September month 2019. We were forced to take out another contract for a router from another service provider as I need it for work purposes. Between 27/12/19 and 20/01/20 nothing happened. During this period my husband was at the shop +-8 times to ask what is happening and each time there is a different excuse. On 20 Jan 2020 my husband again approached the shop again and the lady told me they will resubmit again on 20/01. On 21/01 we found out via the call center that the router was finally cancelled. On the same day the payment of R668 (Dec) was reversed in error. The shop was advised of this. On 25 Jan a payment of R270 was made for the cellphone contract for Dec month 2019 While my husband was busy with the shop I contacted the call center and I spoke to Whiskey. He also came with different excuses and all the docs I must get to prove my payments and when the shop did what and so on. The problem is they are wanting me to pay for something I don't have. On 27 Jan I made another payment of R270 for Jan. Whiskey apologized and said they are going to refund me. I don't want their money as they don't owe me anything. We have our money as the payments were reversed at the bank. Hence the 2 cash payments for for the cellphone contract. On Friday the cellphone was suspended although 2 cash payments were made. On Saturday I went to the shop to find out why my phone was suspended. Apparently the account is in areas. How can this be when I made 2 cash payments for the phone and I don't have the router any longer. The sales assistant that works now for MTN also came to explain how the account works. Parent account - debit order I never asked for 1 debit order. Then the incoming money goes to the children account. Child 1 no payment as I don't have the router any longer Child 2 cash payments as the debit order was reversed. What they told me I told them the same thing. The way to fix this is that the shop admit that they were in the wrong as there was nothing done. They also can not provide me with reports from the technical department regarding the router or any correspondence between shop and the technical department. My phone to be reactive immediately as it is paid for and they have broken the contract by suspending it. Don't make me out to be a **** when you are standing behind the door.
