Double debit, money not paid back within 10 business days

I waited the so called 10 days for money that was deducted twice, I called 4 times, I emailed the complaints department, with no response, I was told on Friday the money will show in my account within 24 hours, needless to say, it doesn't show. I am tired of asking, I am tired of trying to explain to other providers that I can't pay them due to another service provider taking my money. I want my money back, I held up my end of our agreement, my debit order was collected for PL, I want back the other money you collected.
