BAD Service from Homechoice

Before I placed an order I confirmed with them will my package be send by courier or to the Post Office if they send it to the Post Office that I will not place an order. Due to the fact that it takes the Post Office 3months to sort out the packages and it is also not save at all to go there they confirmed that it will be send by courier. So I placed my order and 2days later I received an sms that my parcel will be send to the Post Office. I contacted them and I emailed them to please cancel my order as I stipulated that I do not want the goods being send to the Post Office. I received an email confirming that it was cancelled and my account will be credited in 7 days. Two day later I received an sms again that my parcel is out on its way to the Post Office. I phoned and emailed them again that with the confirmation email that my order was cancelled. They told me that I have to wait for the Post Office to send the package back before they can Credit my account. Which I told them is expectable because I will not pay for goods which I have not received and cancelled. Its been longer then a month and the Post Office still have not received my parcel. And know they are phoning me for payment on that order.
