Frustrated customer

I purchased a stove from Amazon, but it was delivered without the legs. I reported the missing parts on 6 December, and to date I still have not received them. I was informed that the legs would be delivered on 16 December, but there has been no update. Amazon’s response has been limited to emailing the seller and asking me to wait for a reply. There appears to be no proper follow up or control, especially since there is no direct contact number to escalate the issue. Instead of resolving the problem, I am repeatedly advised to return the item. This entire experience has been extremely frustrating and disappointing, and overall it has been a total nightmare. Flush Amazon SA and S & M Household (SELLER) down the drain.
