Landline complain

I had a Telkom landline which was under prepaid waya waya , last year November I have reported the line not working and they have not came to fix the line this year feb they sent an sms that says the are upgrading to wireless phones, in May they sent the wireless phone with SIM card and the SIM cards was not working I have reported from May till today the phone is not working. Yesterday day I went to Telkom they told me that my number is no longer working they have deleted it, is in the archive. How is it possible as I have not got assistant from them.
