Stop messing with my life!!!!

Horrible, I resigned from my previous job end of Aug. According to their email, it was going to take 4-6 weeks to payout. I'm now in week 8 still nothing. I have called them more than I care to remember and they keep asking me to submit the same documents. People marry and surnames change,what is the big deal. I sent all the documents proving my identity yet they still send me the same stupid mgs." Bank automation failed." Do they not know how to update details? I'm so fed up with this company. And it's not like I'm asking for their money, this my money and I worked for it.
