Worst service ever received

On 10 January 2015 I ordered a Fisher Price Bouncer, the order was placed and paid on 10 January 2015. On 13 January 2015 I received a e-mail stating that my parcel was on it's way and was dispatched on 12 January 2014. I phoned [URL Removed] since 19 January 2015 on a daily basis. Every day I spoke to someone new and everyday the person promised they would get back to me. I have only had 3 of the 9 operators got back to me. First there were a few people who have an issue with the bouncers, but after I told them that 2 friends of mine who ordered and paid their bouncers after me received theirs, then it was the couriers who was at fault. First it was Fed Ex who has collected the parcel from their warehouse, but have no record of the parcel, then it could have been Dawn Wind. And yesterday it was the warehouse who either misplaced the parcel or don't have stock. The item is still being advertised on [URL Removed] so I don't understand how an out of stock item can be advertised. I do not want to be refunded, I want the item I purchased as it is still advertised on your website!!
