Incompetant / Worst Service Ever

I have a domain that is registered through M-Web and a couple of business e-mail addresses. Since last week Thursday at around 4 PM my domain just ceased to exist or work. I have about 4 people in the office that cannot send or receive any e-mail, clients that try to send us e-mail just get an error message saying that the domain does not exist, I cannot direct anybody to my website for business. I reported the matter to M-Web Friday morning and have been given the runaround since then. When they realised that they had no answer for me they just said it will take 24 hours to be fixed. So 24 Hours later on Saturday I phoned again, again I was told another 24 hours. Sunday came and went, I didn't even bother to phone. Monday morning first thing phoned again, again I was told to wait 24 hours. It is now Tuesday 24 hours later and still nothing. Nobody gets back to me, the problem isn't being resolved and I have just lost 5 days worth of business for now who knows when this will be fixed. But come month end they are first in line to take money, but when it comes to service you are *****ed. This is what I get for being a loyal customer for of about 13 years, THANKS FOR NOTHING.
