I bought a mattress from Cancun Market in Grapevine mills mall for almost 900 dollars which not even 3 months after i bought it started sinking in the middle. i shifted the mattress numerous times and nothing seem to fix this problem. i contacted them and file a complaint requesting for help. they have ask me for pictures, bar code, i explained them that mattress did not had a bar code when i took it from bag and i proceed to take picture. they denied my claim as my mattress has no bar code and because in one of the pictures i sent it seems that mattress has a small stain. i explained that mattress has no stains so now they want me to take the mattress over to their warehouse which weights around 500 pounds or i need to pay a technician to come to my home and inspect the mattress this for 120 dollars only. i explained that i have an herniated disc and my friends that helped me out to pick up the mattress from the warehouse no longer in Texas and they gave no more options. It seems they going to keep on giving me the run around and this is frustrating as im not even sleeping on the mattress as it is because is uncomfortable. i need help!!
