Horrible service/ wrong delivery

I placed an order for a bed in December. After following up on the delivery time and date numerous times I received the bed on the 6th of Jan at 10pm at night. After enduring the worst service from the delivery team I realized that the base of the bed was the wrong size, the delivery man assured me that he would sort it out and return the following day with the correct bed. They left the bed as I have already gotten rid of my old bed earlier that day. The next day on the 7th I phoned home choice and spoke to the manager whom assured me that it would be sorted out within 3 days. After not receiving any feedback by the 12th I phoned again, there were however no record of my call on the 7th with the manager so I had to log a query again. One week later after still not receiving any feedback I phoned yet again just to hear that I must phone again on Monday. When will I get my correct bed!!!
