Truform bedding shady bed deals

I was referd to an employee who works at this factory who then arranged for me to come and pay a deposit and then later come through to collect and pay the balance of my purchase.. On the day I collected my bed the boss took my money and assured me that should I have any issues the bed is under gaurentee and a 15year warranty... Fast forward 8 months the mattress is deformed and I complain and was told that due to covid they are not doing any repairs. I am sure it should be replaced under gaurentee but I let it slide.. I Hev now been asking for nearly a year and today I speak to a manager there who tells me my bed has no warranty as it was a staff purchase... I was not even aware of that they are doing this to make money on the side and probably avoid tax and those who fall for this are left with a messed up bed
