ADSL Slow speed / Broken Router

I reported my adsl line as faulty in Late November- Throughout December and again in January. I recieved a sms on the second last fault, that it was resolved. I still had on - off internet with a max of 2.8 mbs. I have mutiple screenshots throughout December and January of Speedtest. So last week saturday I reported a fault again. I was assisted today Sipho came to the office and asked for a reset of the line. I was still working on a website for a client. He asked if he could switch off the router - I had no problem with that- and now No internet- at all-. None of my devices can reconnect to my router? He now claims it is a router fault - as I am out of contract with Telkom - I now have to get a new router?
