Telkom again

Back in September I called the call centre to cancel my fibre line. Was advised I could not do this telephonically so emailed the relevant form to the address provided notifying them of my wish to cancel. Received an auto mated response saying they could take up to 21 days to be attended to. Earlier this month I had heard nothing so sent it in again..... no surprises here no action taken, no contact made.

However I then receive a letter stating they will take legal action if payment is not made.....

Please can someone who has some interest in doing a bit of work please get this sorted out.

Thanks
