Line not working two weeks later

I called in a line fault on 3rd Feb. Since working on the problem, my adsl stopped working in addition to my landline. I received an sms on Friday 13th to say the problem is fixed but if there's still an issue, to escalate on their website. The site does not allow for letters in the reference number field. I lodged the escalation and was told Telkom would contact me shortly. I have not heard from them at all. My reference number for the fault was 619CRK030215.
