Unreliable hosting services - Good luck trying to get hold of Support!

From the 10th of November, my Reseller package - all files were removed because (I assume) a technician changed the settings to the home2 partion as only read. So all my clients emails and websites just stopped working and disappeared. They fixed it (so I thought) - Emails stopped working at 12:00pm on the 11th of November, they can send, but not receive. I quickly phoned in as my clients rely on their emails. I get told all of a sudden now my whole shared server is experiencing high volume due to backups. They started receiving their emails again today, the 12th around 11:00am - Question is, where is all the emails inbetween? I was promised nothing will be lost, and I quote, "If your services are hosted on either of these servers, you may experience intermittent slowness or temporary unavailability of websites and emails. Your data remains secure and unaffected."

Now I am trying to phone for support as the tickets don't get attended to - I keep on the line then it cuts off. Then I phone again and I wait in line till it cuts off again. This is utter bull****. I have lawyers as customers, this is not on!
