Very bad service

I placed an order on the 17th of October on the 18th the item was dispatched from cape town , on the 22nd the item was in middleburg at the courier company on the 25th I called the courier company to track the parcel I called home choice on the 29th tracking the parcel the agent that helped me informed me that the item is being returned to cape town because there was no one to sign for the item which made me very angry to me because there was someone at home the whole day i said it's fine they must not bother returning the item to me. The next day on the 30th I went to buy the oven cash from another retailer then I the evening I received a call from a delivery guy that they have my parcel I told him to return with it because I don't want it anymore. I emailed home choice was told my account will be credited on the 31st once the item is received. I checked my online account then I realised I have been charged for the oven that I haven't received that was never in my presences on my statement . I called homechoice on the 11th I emailed home choice again no response. mid day on the 12th I called spoke to agent called zukwisa told me the item has been received by them but my account has not been credit she will call me back at 13:30 but never did. When I got home I requested home choice to call me argued with an agent whom now told me the oven it's still on route to them. Told her I need to settle my account I need the actual amount I owe told me i must wait till my account is credited. The next morning I received an sms that my settlement amount is R4500 which I dispute my balance is R1500 ..I didn't receive the oven so I want it credited urgently how do they charge me for services that they didn't render firstly and the courier company they using has bad service the parcel was sitting middleburg for 10days distance between witbank and middleburg is 20min drive. And my online account has been blocked .Seems my complaint has fallen into death ears but when they want us to buy they aren't go out of they way to give us good service. It's almost 2 weeks now the item should be back in cape town ...can my account be credited.
