Incredible Connection delivers canceled orders & does not refund.

I purchased a tresle table on the 31st March, the table did not get delivered in the time frame it was supposed to & in turn purchased another table from another retailer & canceled the order from Incredible connection. The delivery guy kept trying to deliver the order & I told him it was canceled, he messaged me 3 times that they keep handing over the desk to him to deliver, & every time I told him the order was cancelled. On the 24th April, the table got delivered to my son at my address, which he was not aware that this order was cancelled, I have contacted incredible connection several times informing them & emailed. I whatsapped them so many times as well & they confirmed that the order was cancelled. Spoke to someone in the customer service they confirmed that their warehouse was informed of the cancellation. I even emailed the manager Louisa of customer service, & no one is responding. Every time I phone customer service all they say is that they making a note. I am shocked at the level of this. It's been 3 weeks since I cancelled this order & not getting anywhere with this. Someone emailed me for pics of the order, I sent, no response further. Someone then called & said they noticed the the box was torn on the corners, which I said it was delivered just like that, I haven't moved the parcel, its exactly where the delivery guys left it, & then again no response further. I am disgusted that I have not even received a response from a manager. I will never ever buy anything from incredible connection again.
