These are very typical of the issues you have when a service goes live, especially when external events force your timing. I bet these will all be sorted out within a week at most.
From your mouth to God's ears. :-) I expect that it will take more than a week, but the problems are definitely fixable. These are not issues associated with a lack of integrity or fundamentally careless attitude, but with a new company that needs expertise in something that it lacks expertise in. I will probably try Paxum again in a couple of months if I see reason to think that they've fixed the problems.
But not right now.
