Big problem with Tmaxhost.com

I am absolutely gob-smacked at what terrible and shocking treatment I recieved from Tmax Host (tmaxhost.com).

1. A client contacted me to say their website had been down about a week, I hadn't recieved any notification from Tmax.

2. Had to raise a support ticket at Tmax and after getting a few days run around, was told the domain was involved in spamming, and had been suspended, and that "we need action plan".

3. The domain, owned by a 60 year old woman in the countryside, as no IT skills whatsoever, so I told them spamming was immpossible and what were the options, and what is "action plan".

4. They replied, I was not taking the issue seriously and hadn't given them "action plan" and the domain is now cancelled.

5. I was upset, the client is upset, and I asked lots of questions, including a question, "could anyone at Tmax have taken the password?"

6. Then Tmax suspended ALL my domains, because "I accused them serious offence". I didn't know a question could be an accusation! But, now all my clients, their businesses and livlihoods are affected.

7. I demand that all put back live all the innocent party's domains, but they refuse, and now don't even answer my emails.

I find it truely beyond belief that a company can act like this.

What actions should I take now?

any comments?

First off find some other hosting ASAP. Your clients are the one affected and you should give them as little downtime as possible.

Here's a harsh lesson to learn. Simply look at the website. If that website doesn't shout at cheap crappy hosting company I dont know what does.
Your host is your most important thing, make sure you can rely on them.
It pays to do some research into hosting companies. Take the time to ask people about their experiences with particular companies, don't just go off fake testimonials they have put on their site.
