Not refunding delivery fee of damaged goods

I ordered a gift for my niece on the 1st of Dec and paid for next day delivery. When the product was delivered it was faulty. I phoned and asked for it to be replaced same day, because I needed it for my niece's birthday. I received a call back saying they don't have stock so they cannot replace it. I was furious, because how do you explain to a 4yr old what happened to her gift? Takelot said they will collect the faulty item the next day and give me my money back and the delivery fee I paid as some compensation for the inconvenience. After numerous phone calls and complaints and allot of apologies from Takelot the item was only collected on the 17th of Dec and I only received my refund on the 1st of Jan!!! A whole month later! They only refunded the product, now they refuse to give my delivery fee back. So I had to pay for delivery of a product that I could do absolutely nothing with!! And the 'compensation for inconvenience' I was promised is now not forthcoming. Extremely poor service!! I never had this disgusting service from [URL Removed] Since Takelot took over their service is none existed!
