Bay to Bay Appliance Multiple service calls, NO REPAIR COMPLETED Tampa Florida

Have a home warrenty for appliances and Bay to Bay is their service provider.  Filed for repairs two months ago for an appliance that has not worked.  Bay to Bay has sent out multiple service techs over the past 2 months (5 calls altogether so far) with appliance still not working.  Each time they claim it could be something else.  They check, order a part which takes over a week each time and still not working or repaired.  This company obviously does not have skilled workers that are capable of doing a thorough check of the appliance (in our case a stove) to diagnose and find a repair solution.  I would definitely recommend finding another company if any appliance repair is needed.  We are very dissatisfied!
