Have any neighbors used either Perla's Appliance (Monongahela Ave, 15218) or Appliance Warehouse (Binghman St, 15203) for repairs/service to their ovens, or other appliances?

Our house came with a Five Star gas range, and these two local appliance companies are who Five Star says we should use for repair. (The gas oven will not light.) 

The reviews of both companies on Yelp and Angie's List are very mixed, so was hoping the neighborhood experts would be able to chime in with their experiences.

Many thanks,
Em
