What is going on

Firstly...I went into the shop to ask the people working behind the tills(at the back of the shop)to ask who they use (what company) for credit-and no one could give me an answer---You use Rainbow finance....secondly...I purchased a washing machine and 3 weeks ago I went to the same shop, same people behind the tills and asked them that I want to settle the account and that they should give me the settlement amount--they told me that the system was offline-I asked to speak with the manager and not one of the four sitting could answer me about the whereabouts of the manager...ok...so...I phoned head office and they helped me with the settlement amount and I went and paid the amount and the lady said that she would stop the debit order as soon as I forward the proof of payment to her--and I did...but...House and home still debited my account...so I phoned in and complained and the lady said I should go to Fourways and collect the money...I went there today to the same 4 ladies behind the till and they told me that they don't have money to give me as they don't have any money in the till---this is pathetic!!!...I drove from Broederstroom to collect the money only to get NO money...
