TWO MONTHS GOODS STILL NOT DELIVERED

I bought sleeper couch on the 7th September and Bed on the 9th of September and both were paid up cash.

Now is November the 4th they only deliver sleeper couch and wrong colour. I still didn't get my goods and when I ask for my refund with interest because for two months my money was setting on their account it looks like they are not interested and they just give another promises that is also affecting my son because I bought this bed for him. I am now in the state of getting legal advice.
