NO feedback or service

We bought a restonic bed in december 2014. We are on the road for at least 6 to 8 hours a day and need a good bed for a good nights rest. Buying the bed was a breeze as always excellent sevice! Now 8months along the line the bed starts to sag in both sides. Its been 2 weeks and 4 days since we reported the beds default. Even took pics and send it to the sales lady. Or else she had to come to our house and take pics. When I contacted her she said the complaint was logged and they are waiting for the fax from restonic to replace the matress. We went there yesterday and she said the fax is on ots way as we speak. And the matress will be replaced before 5o clock.... Well its 9h30 next day NO reply. She's not picking up the phone, she won't give me the reps name or branch at restonic with whom she apparently spoke. Bears is a a BIG NO NO NO on after sales!! I will never buy even a kettle from them. Very easy to thake my cash money for the purches but BAD on helping with a problem.
