Complaint for a Serta Mattress

I purchased a SERTA mattress from Anna Marie who is the sales representative for Beds for Africa (Centurion), at the Home Expo in March 2015 (the mattress is under waranty). For the past 6 months i have been experiencing lower back pain and have such been recieving medical treatment. I called Annamarie (2 months ago) with numerous e-mails that followed (with no responce or feedback). Eventaully i contacted Serta myself, who had then sent out inspectors to inspect the mattress. The inpsectors where in agreement that the mattress had defaults and they would submit a report to Serta. Beds for Africa/ Serta was to contact me (within 3 days) and that was 4 weeks ago! WIth no repsonse of feedback to date.<br> <br> I am still experience pains in my back. This is unnacptable service escpecially condiering that the mattress in under warrnty. It should be the responsibility of Beds for AFrica to follow up an keep me updated on progress. I am expecting a replacement and new mattress.
