Nonsense Service!!

I bought a bed online, paid for it in November, to date I have not received it, sent an email to enquire about my delivery there was no response, I then called in some time in December and was advised that they had attempted delivery but they could not find my place and I should then make an arrangement to come and collect it in Cornubia, mind you I stay in Stanger and I do not have a vehicle to pick a bed up in hence I bought online! I advised the person I was speaking to about this and she said she would get back to as they do not have any deliveries scheduled for my area... How? When my my bed has not been delivered yet!.. I called in 2 days later to find what was going on (she did not get back to me) to my surprise apparently she noted down that I said I would be collecting... How when I don't have a Van?, the guy then says he will get back to me he needs to check something, I let them be during the holidays thinking when the year kicks off they would be on top of their game... I called this morning and I find out that a bed that I had paid for in November is now OUT OF STOCK! How guys??
