Customer Reap Offs

I have bought a medi spine symphony bed mid year 2020, I have since only used the bed for a couple of months as I relocated to Soweto but have since April came back home. This mattress is the worst and has poor quality. I have recently tried to contact customer service via email regarding the bed'mattress as it collapsed or damaged and I notified the customer consultant who helped with the sale of this bed. Since I bought the bed I have experienced health problems and have never felt comfort which is caused my the collapsed/damaged springs in the mattress or the poor quality of the mattress because the base is still intact. I have today after all the complains I have launched decided to confront the Store manager and find out about the progress of this matter. However I was told my complaint has not been attended to and there is no form of information to show that the complained was launched. The Store Manager advised me that because of my last complaint about their bad service that the bed was marked down so the insurer may refuse to exchange the damaged mattress. "How is that my problem"? Also that I will be charged extra cost as the insurance only covers a the amount which the bed was marked down to. The initial price of the bed was R4 999, 00, however the manager has told me that based on my weight I should have bought a bed that is priced higher to get quality. So my understanding here is the consultant sold me bad quality bed which should have not been sold at all. Customer Consultants should make sure they cover all the specs of a product and make it known to the customer before selling them ******* just because it suites them. Still am expected to continue paying the stupid insurance and the monthly installments even though I was sold bad quality at high purchase. With the monthly installments, I have way passed the marked down price. I am very angry and upset as these people do not understand that it is the consultant's duty to make sure they take care of their customers and give them value for their money. Lewis Stores/Bears advertises themselves as one of the leading furniture Stores selling only good quality but I have since realised that this is not true. They will do anything or sell you ******* just to push sales but do not care about their customers at all. Their service is shockingly bad.??? no customer service skills at all..
