disgusted

account was written off at Lewis stores Eldorado Park while making regular payments every month.got a call from Landau attorneys and reached an agreement with them and was told by them that were the only company that would be debiting me.Since December 2017 Lewis and Landau attorneys have been taking monies and I'm being spinned different stories by the store and their head office.what am I to do in a situation like this as Landau assured me they would talk to them and the head of the finance dept at Lewis Eldorado Park told me the reason for the debit in December was to make their books balance.I have a big fear that this would be happening every month going forward and both parties would be gaining from this.please help as I see this as *****
