Still waiting for advice.....

I purchased 4 chairs, which were delivered on the 25th of November 2021. I immediately noticed that a few (9) of bottom rubbers of the legs of the chairs are missing. The chairs are not stable. I ask the delivery guy (a very nice man) what I should do, as this is my first time purchasing online. He advised that I should call the customer care, which I did whilst he was still closing up his truck. I received a reference number from a Jamie, who said someone would call me to advise what I should do. A week later, on 3rd December 2021 I called the call center again, speaking to a different person (forgot his name), who said he would call me back in 10 - 15 minutes and advise what would happen. He called me back, as promised, thanks. He advised that someone would make contact with me soon in respect of my chairs. I'M STILL WAITING.... When will I get proper advice so that my chairs can be used?
