Poor customer service.

I bought a queen size forty winks bed on the 4th of July 2025 online and it was delivered on the 5th of July 2025. The bed is not comfortable and its a bit short compared to my height so l requested for the bed to be changed to extra length queen size as well as an upgrade to pillow top but the customer service is bad. I logged a complaint on the 11th of July 2025 and today its the 14th of July and my issue hasn't been solved. I am disappointed considering the fact that l paid cash and l am even willing to top up the money so that l get forty winks ActiveZone Luxury Pillow top Medium Bed Set queen extra length. I even called Dial bed this morning but till now l haven't got any response. I feel like they are trying to buy some more time so that after 30 days they will tell me a different story.
