False Advertising and False Promises ,Dont Support Rest Assured,They certainly wont support you

I have purchased a Rest Assured mattress From Bed Store ,Springfield DBN, in 2017, It cost me R6000, in 2018, the mattress started to cave in on Both sides that we sleep on, i called the store and complained ,they referred me to a Rest assured customer service office, i spoke to Billy a manager there who sent an agent home,they did their investigation,but didnt contact me for months, i called again, asked the status of my query, the agent who did the investigation, was no longer there ,Billy said, so they sent another agent, he took pictures etc, no response at all from rest assured, i called september 2019, now my mattress was in such a worse condition, to the extent of me starting to experience neck and shoulder issues, im currently on a 12 week neck and shoulder program,i ve been getting a ru around,finally they reported yesterday(after 3years) the bed to be un hygienic, i asked , how does that affect the 15year warranty, and their promise to offer a solution when experiencing discomfort caused by the mattress, its been 3 years now, we cant sleep on the mattress as the springs are collapsed and can its easy to notice. They insist theres no defect, and refuse to assist ,and insist its unhygienic, i have called many occasions to assist us but all they do is evade. No correspondence was sent to us so that we could make a temporary plan, but i paid R6000 for this and its only 3 yrs , This is **************** , The Mattress is defected ,no help given to fix it, they need to provide proof that it is in fact Unhygenienic, how tdoes that constitute for defective Springs?Come on, They are ***** . Is it because im Indian and this is a Pre dominantly White Owned Company?? It seems Like,i will in future ask, consumer watch and wendy knowler to help get to the bottom of this, how many more customers are duped into false promises?They have very unhelpful employees there too ,rude and arrogant, unhelpful .lying.. Roland Francis Billy waiting for senior manager Marc Baines, To respond i dont want a New mattress . fulfil your obligation that offers 15year warranty on defects.
