Shocking Service, line down for a month.

Shocking service. My line has been crossed with someone else since the 22nd of Dec and I have logged mutiple complains, faults and escalations. None have been seen to. Phoning the call centre they keep putting down or on hold with no feedback. Always just escalating, but to no avail. It is now the 17th of January and my line is still crossed. People trying to reach me get through somewhere else and my line at home is dead. My ref number is 27ARK221215. I cannot believe the utter shocking level of service by this company. Nowhere in world can a business of this terrible calibre be running, except in South Africa of course. It is beyond belief how shocking the service is. I work for a Telecommunications company and if our service was anything as bad as this, we would be closed down by now. I don't know how this company is still standing. It is beyond me.
