Telkom e-mail - no commitment to send technician

We purchased a new pc a month ago. I phoned Telkom on 18/11/15, ref. no. ***. I told them my e-mail is gone. Frank said they will send a technician out to us at no cost. On 20/11/15 I phoned again and spoke to Celo. He said that Frank did not follow through on the case and he will only initiate it now. On 25/11/15 I phoned and spoke to Xolani who cut me off. I phoned 5 minutes later and spoke to Thomas. He said the technician will come out to our home \one of these days". In the meantime I am cut off from everyone. This month I will receive no bank statement"
