WORST BED EVER!!!!

I bought a bed from this shop in montclair a month ago, paid good R6000 for the bed, the mattress sinks in, very uncomfortable have been suffering from back ache from the very 1st time I slept on it, I have sent them an email only for them to say 1 of their consultants will call me! I’ve been very patient with sleepmasters and I’m starting to loose this patience!!!!
