Cancellation without my request!

I installed a 20mbps DSL line about +- a month ago and I cancelled my LTE Broadband. So this morning I woke up to no internet to only find out that they have cancelled my internet without any requested from me. I have been on the line with them the whole day trying to get this sorted out but no one can be of assistance to me. I was told at 1 that a manager was going to get my internet reinstated and call me within in an hour. So 2 hours later nothing and called again. I am on the line now for 40 mins waiting for another manager which is not answering her emails. I am working from home and I am unable to work due to a Telkom error which they are *********** to solve.
