Crown Jewel is a royal pain in my back- literally

I bought a Sealy 152 XL Lannister XFirm Mattress from the Bed Centre in Tyger valley less than 7 months ago.

the first 3 months were super great and comfortable and then i started to notice that the mattress makes a hole in the middle and that my partner and i are being thrown unto each other at night and that we are forced to lie in a dip / ditch the whole night.

at first i thought it was my imagination but it's gotten progressively worse as time has passed.

i have been going to a chiro for 2 months straight now, i have terrible back pain and it's cost me R10 000 already in chiro bills to try and alleviate my situation.

I have contacted the sales woman (Cheryl) at the bed centre and she has not been helpful in getting someone to come look. this is a poor quality product for a high price and the worst part is that the internet is actually full of similar reviews for the Crown jewel range.

i want my money back and i want you to pay for my medical bills too.
