*** arrears from installments to cash orders not authorised

I am highly dissapointed in homechoice and I feel that I no longer want anything to do with this company. I recently placed cash orders online and selected EFT as I have an installment account with them. I however forgot about the cash orders until I went online and saw that one of the orders was dispatched. My credit was also lower than the week before. My installments debit went off and the accountant decided to transfer the money to the cash account, which is ridiculous. I contacted HC and was advised that I am in arrears which I could'nt understand as my debit went off. The first lady I spoke to Ms Boniswa Stryama got so frustrated with me where she kept arguing instead of listening to me. She was so unprofessional. Also I never authorized for the payment to be transferred. putting myself in arrears. The matter was escalated to Theodore who got someone to contact me from accounts. The lady said that she will sort the account out and because the orders was dispatched I can either pay for them within our agreement or I can return them. But she will make sure my account is rectified. I then got calls from their collectors to advise me that I am in arrears and I am so fed up now because I was not supposed to be in arrears. then this lady got a fine cheek to tell me that if an order is pending they can transfer money to that cash order. A cash order is not debt, when I told her that the arrears is an internal problem yes if you want to discuss this further call customer service. Like hello you called me not the other way around surely they should keep some record as to what is happening on their customers account. They don;t even do a courtesy call just to check if a client will still be paying for pending orders. They just do what they want to , to get money from you. I won't suggest anyone to do D/o from them or take anything on terms as they are conniving and will cheat you from your money.
