I have come across Bad Service but this far worse

Karabo who is apparently the person who is dealing with my query, the person who is responsible for resolving client queries and issued with complaints is arguably the worst in service have come across in this position. In all instances she would contact my wife or my home phone and leave messages there instead of contacting me on my mobile or via email. She has been given my details on numerous occasions but insists on contacting my wife or my home number which does not get answered during working hours. After more than a week of silence, she once again she calls on Thursday and leaves a message on my home number. She made NO ATTEMPT to contact me on my mobile nor did she make any attempts the following day. When I get home on Friday afternoon and return her call after hearing the message, I am told she has left for the day. She doesn't work over weekends and I leave a message for her manager to call me which doesn't happen either. I call on Saturday and spoke to Innocent who was the manager at the time who said that someone will contact me on Monday. I am still waiting for this call. It seems that this shocking service doesn't stop at her!
