Accepted a job in another state, haven’t heard anything from them in 4 weeks, no confirmed start date. Another company made me a better offer in the meantime.

So I've moved from Minnesota to Colorado. Before I left I accepted job offer from Company A, I told them I would be able to start on 5/22. No response from them confirming that, in fact I had to remind them a week later that I accepted their offer and asked if we were moving forward, HR got a hold of me shortly after that. So I filled out all my HR paperwork, did background, etc. Sent the forms back via email.

Silence, no reply, nothing, still haven't confirmed 5/22 for a start date.

About 3 weeks go by, I get a call from Company B, they offer more money plus vacation time. I accept. Do drug/background. Still nothing from Company A.

So today, about a week later, I'm still waiting on the results for Company B, but Company A emails me saying they expect me in the office on Monday, 5/22! Wheres the fucking communication?

I've been in Colorado in my new place for less than a week now, but I never said anything to Company A about my moving plans.

So, to the point, should I go along with Company A until I get a start date for B? Or ditch A now and hope for the best with B?

A is a small company, more potential for training, and interesting work.

B is a big corporation, with more pay/benefits.

I really don't like the way A has communicated. They were fine until I accepted their offer, and I turned down an even better one for them.

I'm fucking tired of the way these companies treat people, and I'm really thinking I should just take the offer for the most money.

Thanks for any input!
