Sleepys Mattress Not honoring warrenty and useing 3rd party that will not respond mattress only 1 1/2 years old Elizabeth City North Carolina

I purchased the mattress on may 16 2014. started to notice sagging and a hump across the middle. i talked to a sales lady, donna, august 14 2015  and she said i have a claim as the company carolina mattress guild went out of business and has had other complaints.she called customer service and i  was told i had to go thru a 3rd party called mattress marshals! ok, so icalled and they told me they were sending a kit to test the sag. that took almost 2 weeks. when i got it i had to take pictures and send them back to them via thier website. i do not have the knowledge or means to do that so i went back to sleepys and told donna what happened. she called customer service and the said they would send someone to my home and that they would be calling 5-7 days. no calls. went bato sleeps and doona called customer service again and she was told they had my address at the time of purchase. ok, so i gave them my new address again and she said she updated the information and i would hear from them in 5-7 days. on the 7th day i got a call from mattress marshalls and the gentleman said he would be at my house 10/2/15. i made sure he had my right adress because i had to give him directions. he never showed or called. so i went back to sleeps and told donn what happened and she called customer service and i was told the would have someone call me again that donna had not updated my information correctly. well when mattress marchalls called the sure had it right. so i call customer service myself very upset and all the would say was sorry, we deal with a 3rd party and thank you. i call donna then and she gave me the president of the companys email address which i have not been able to get thru.instead i got your web site. saturday evenint the 10th of oct i recieved a call from customer service. peter kept saying how sorry he was about all the problems but he assured me i would hear from mattress marshall mon or tues. guess what. nothing. i am really disappointed in sleepys but i also dont understand why they do not honor thier warrenty or product. i am not done here but i do hope you can help. i am going to continue to locate the president david acker and will be in touch with the local media.
