GUARDSMAN VALSPAR CORPORATION Paid for fabric protection/spot remover, Guardsman will not colmply due to my "wording" GRAND RAPID, Michigan

I had paid for the spot removal on couches when purchased in 2008. 2010 i started contacting Guardsman to have this issue resolved. I was denied at first because papers were received to late, then  I was informed that the "wording" cleaning meant they could not service me. I went to store lever on several occasions and was told the same. An employee at Gaurdsman informed me due to my wording the plan was not obligated. All I am asking is for some stains to be removed from the couches, not a cleaning on the couches. I was informed to get couches professionally cleaned then  contact Guardsman to come to remove what ever was left by that company. I would have to shop proof of this service before Guardsman would comply.
