Terrible Service & No Response

Two weeks ago our Neotel email address disappeared and would reflect 404 Error or disabled came up. For two weeks we have been telephoning to rectify this matter, to no avail. Several reference numbers later, further enquiries, all we have been told is that Neotel migrated to another Server and our email has not been loaded onto the new server. Eventually I was told our complaint/query had been escalated, on 25th November, Ref No. TECH*** direct to the technical department who would get back to us in 24 hours. of course, this did not happen. Telephoned again today 27th November, to be told nothing had been done yet, the technicians do not work at weekends, and could not tell us when we could expect to be active again. Upon our insistence for some time frame we were told within 48 hours - working hours that is !!! From Monday !!! Surely with such a serious fault and big error on migrating to another server, the technical department should be working around the clock to rectify the matter !! No email service, very important emails for our business, no answers, no positives, BUT we do not see a reduction in our account ????? Very disappointed and angry.
