I was under the assumption that everything was fixed to your satisfaction. I'm sorry to hear that your situation has only changed and not really improved.
When I said I hoped you thanked him, I meant the manager only. And only because is is making an effort to fix the problems.
After reading about the issue you have now I've changed my mind. I hate it when companies don't fix the problem but instead put a band-aid on the problem. Either fix the problem properly or don't fix it at all.
Good luck with your progress. Don't let this bad experience ruin everything for you.
