My call, callbacks & emails are ignored

on Saturday 28 February two payments were incorrectly deducted on my bank. I called so they can reverse the payment but the call centre was closed. i requested a call back and i sent an email as well. Again this morning i called, was on hold for a long time so i requested a call back and i sent another email as well - still no one has responded but i can see my email was read. <br> I don't have extra money on my account for double payments I need the second payment to be reversed immediately but i don't know what to do anymore coz it's almost end of day now and one one is willing to help me. I am going to be short for my other debit orders. I am very unhappy with the bad slow service.
