Sears Home Services Charged, when no services were provided. Euless TX

I contacted Sears Home Services online around August 5th, 2015 to come out and repair my refridgerator and a garbage disposal unit.  Their website says the charge is $84.99 for the trip charge and it would be included for the repair.  They did not ask for model number, age or anything other than brand name on their online site.

The repair tech arrived and called me to tell me that the part to repair the refriderator was no longer being manufactured.  I asked him about the garbage disposal unit and he told me he does not have the skillset to repair garbage disposals, so I would have to pay another 84.99 (including tax) for another tech to come out and fix it.  Sears knew about the garbage disposal unit, but clearly wants me to pay nearly $170 in trip charges for them to repair my appliances.  What a rip off.
