Royaloak Furniture — pathetic customer service ever!

This is one of the worst buying experiences i have ever had in my life. It's been 5 days that i have been trying to talk to someone from the installation team. My chair was delivered 5 days before, and till now no one has even called me regarding the installation. Called one of their customer care number about 20 times, they pick it up and no one talks. The whats app number responds once in 3 hours and not a single response was to the questions that i asked.
Then i tried calling another customer care number, which put my call on hold in between when i was speaking.
One thing is certain. This is the last time i am going to purchase from here, and i am going to advice my friends also to not every buy from royaloak.
