Unsatisfactory business ethics

Move line, 15 June, arrangement for 8 July made, received confirmation via sms, no one arrived. Made contact again 13 July, arrangement made for 27 July. They arrive only to tell us that the line has been ****** and that Telkom is aware. Rudely stated that its not their responsibility and we should rather find a new supplier. Its not our responsibility to contact the technical department however made the call, waited 35 minutes and that is enough. I run a business from home and depend on the phone and internet lines. We get billed every month for a service that is not provided. Why should we contact the finance department to resolve. This has gone to far. Please resolve this issue ASAP. Please ensure a new line is installed for the service you should provide and make arrangements for services paid but not rendered. We have made more than 10 calls to get this resolved. If this is not resolved I will escalate this matter as far as I can take it. And to make it worse, this is the second Hello Peter complaint with the same issue.
