Bad customer service!!!!!

I purchased a Holts product Ultimoil Interior Dazzle UDAZ3 at a premium to other products from Sheen .The cannister doesn't have gas in hence it can't spray........I phoned the customer care service ********** .The person in the department assured me that the sales rep would contact me within a few hours..........I'm still waiting . Why display a customer care line on your product if you don't respond
