Disappointed customer

Hi good day, about 5 months ago I bought a base and mattress set from blueroute house and home, the sales agent was S Leeman, she sold me a restonic do not turn mattress as I have a problem with my back, she told me I must rotate the bed the 1st 3 weeks the once a month which I have been doing, but the mattress is still sinking and becoming hollow. I went to house and home last month but Mrs Leeman was not there they gave me an email address to send pictures, which I did twice already and I'm still waiting for feedback, maybe to them 7000r is not alot but to people like us it means alot cause we work hard for our money, if they there only to make sales and ******* innocent people like us, by using all fancy words and getting us to give them sales then they wrong, I need a response from them ASAP as they pulling so my warranty wears off. Really unprofessional, really think twice before using places like that we're we trust the name to quick.
