Worst Customer Service

I had the worst experience ever with Telkom, I was nominated for a promotion for a router with additional 2 sim cards at an expense of R230 a month. Everything worked out accordingly. I paid the router monthly until Telkom stopped deducting money from my account, I went into the Cresta Store to settle my arears and reported that my one sim card is misplaced, they claimed to have done a sim swap however the new sim card I received does not get loaded with data, a few months later the problem persist and the charging point of the router broke I reported the case and they informed me that it only has one year warranty and that they cannot fix it, I still continuously till date paid for a router that isn't working, no data being loaded and worst of all no payments being deducted until I went in to the store to enquire about a default on my name and they advised that I am in arears of R980 and informed me to settle it, I settled the arears and requested once again for my router to be fixed and they told me that it is under warranty and will not be fixed, I than urged for it to be canceled the guy that assisted me at the telkom store in cresta informed me to first make a payment than I should call back in 3 days time to cancel the contract and it will be canceled and the default will be removed I did exactly what he requested but when I called the telkom line they advising me that they will deduct two months payment. My concern is that I am Firstly paying for something I have no benefit from and secondly I am still paying for something I requested to be canceled I am disappointed in the services I received and will be taking this matter to the ombudsman and will not be paying a single cent.
