Lewis keeps disappointing

Firstly I had a delay in getting my cashback and had to lodge a complaint and finally got it. One of the items I purchased was a bed (this was the main reason I opened and account with Lewis stores. I was told they do not have stock and needed to wait till end of January which is accepted. I have yet to receive the bed and have followed up with the store on 1st Feb and advised that they were expecting stock on the day and the manager would call me later on that day but I have yet to receive a call or may update of the delivery of the bed. I have also emailed their head office and the store yesterday but still have not received any response from either.
