Bad customer service and refusing to refund monies owed to me

I have a furniture account with the above store and they are meant to be debiting my account on the last day of the month, this previous month the store in question Lewis debited my account 4 times which was three times on the 30th and then again they debited on the 31th. This situation has left me with nothing to provide for my family, am unable to meet my the debits and not able to put food on the table for my children. I have spoke to a number of them went to the store at Pritchard and spoke to Mike who is the branch manager and was referred to talk with the head office and the consultant have been very rude. I write the review with great hope that I get help and they refund me the money owed to me, I have been promised to be since Tuesday till now. I really need the funds so that I can survive with my family.
