How big is the tech company? My offer letter was retracted after me having signed it as well. Their reason was that due to all of the people would sit in one single room(it was a startup) adding one more person would breach their fire hazard safety threshold. Point being, if the company is big and even somewhat reputed, an email is not really bad right now. Give it a 2-4 days and if you still dont receive a reply, just go for it
