Dissatisfied and disappointed

Very disappointed with Sealy and sleepmasters..... I bought a bed online, I received it on the 12th of August then on the 13th the next day it was snagged on the one side.... I logged a call with Sleepmasters then the fault was acknowledged the mattress was faulty... Now I'm requesting for my refund which I'm liable to according to their terms and conditions but they telling me it's not possible since there is nothing wrong with the base, I bought the bed as a set...now I'm forced to have I don't want because of base for base that is faulty... Ref no***
