Extremely Bad Service

I ordered a heater on Sunday and was unable to change the delivery address as the heater was supposed to be delivered to my mom in KZN and I am in Cape Town. I called in on the Monday to change the address and was told that the order would be cancelled. I then received an sms on Thursday informing me that my order was despatched despite numerous attempts to change the address. I then contacted Homechoice to inform of the change of delivery address and was told to upload the proof of delivery address I wanted the delivery to be dispatched to, which I did and was told not to accept the order if delivered to the wrong address. To my surprise the order was delivered to security at my complex without my consent, the delivery company did not even bother to find out if they can leave the order at security and the staff at Homechoice that attended to my query were a total waste of time, rude and useless. I am now stuck with a heater I don’t need and if it is not collected by Monday 22 July 2019, I will throw it on the street as I didn’t take possession of the heater and I did not give consent to this delivery. The order was cancelled long before it was dispatched. I will never order from your company again. I now can’t keep this heater at security until the unknown day that it will be collected by Homechoice and will now have to make time to be around when it it collected, yet I had ensured communication well in time to avoid this situation. Your staff is rude and useless in helping with the cancellation of the delivery or communication regarding my query.
