POOR ASSISTANCE FOR WARRANTY FURNITURE REPAIRS

I am frustrated with Coricrafts repairs process. They do not have a call centre for assistance in this regard, they strictly work via email. I emailed them my repair needs on faulty furniture 3 weeks back and it took days to get any response from them. I have had two people email me back and I reply instantly, only to have another stint of silence from them. How does one them to assist and understand the urgency of needing a bed and couch sorted????
