The worst experience ever!

On numerous occassions I have had my bank account debit on the incorrect days and for the incorrect <br> AGREED amounts. They voice recorded authority agreed to is blatantly ignored causing me financial trouble and unnecessary stress!!!!<br> <br> Funny how they can place money into your account in 10 mins but when the error is on their side you wait over a week to get your own money back and they do it over again not even a few days later!!!!<br> <br> Is there no legal action that can be taken for them just debiting my account as and when they feel like it?<br> <br> Again I was debited last night (Thur) when the agreed day was a Monday (and they already collected for this week on SAT!!!!) as I receive weekly wages due to being a temp, and I had to loan money from my dad to get me through which as it cleared boodle just helped themselves!!!!<br> <br> I have tried for over 2 hours to get through telephonically with no joy!
