Cancellation of ADSL without informing client

I cancelled my subscription at voxtelecom for adsl and data and they released my line back into the holding pool on Monday 21st May 2018. I phoned telkom on the 23rd to apply for a 20 meg line at telkom. I was told by Cameron that the line is not in the holding pool and that I should wait for a sms confirming the line in the holding pool before I can make my application. I phoned again on Friday after still waiting for a sms - telkom's system was down and I was told to phone later. I phoned again on Saturday moring just to hear that my ADSL line was cancelled by telkom because it was not used. Now I have to apply for a new line and pay for installation and wait 14--21 days - this is not acceptable as it was not my fault that I did not receive a sms and was not helped with an application on Wednesday 23 May.
