Do they have any websites in their portfolio? From what you've said they sound like con artists to me because no professional web designer should have problems with the basic things you've described. If you PM me their website I'll take a look to see if their portfolio looks legitimate (it's amazing how many companies have fake portfolios). If they're falsely advertising then you may have a stick to beat them with.
you have to assess whether its worth continuing with them.
it might be cheaper to cut off from them now and move on to someone else. This about whether its going to eb slow and tortuous for ever?
I would be interested in what they/he/she are doing too - could you pm me your link please?
some designers are not great, but you could use a cms and amend the website yourself which would be easier and cheaper for you
