Reviews of Perla's Appliance and Appliance Warehouse?

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
