Home Choice - Poor Customer Service

I have a formal complaint about Homechoice my account was not debited as the set date, and i was called by a consultant informing me that they could not deduct as there were insufficient funds in my account which is completely not true. I then received an sms to notify me that i cancelled my debit order. I then call Home choice and speak to another consultant and she confirms that the debit order did not go off and it was an error from Home choice. Now they will deduct my account including the Interest for the payment not debited. I do not see why i have to pay more for something that was not my fault.Also notifying that i had insufficient funds in my account which is a lie. I am not happy with the consultants nor I am happy with the way this account is being handled. Home Choice will call you a million times to buy from them but they have no idea the meaning of customer service.
