Hi - I would like to report a serious dead zone for Verizon in a busy commercial and institutional area of Mamaroneck, NY. It is centered on the Stop & Shop supermarket at 1326 W Boston Post Rd, Mamaroneck, NY 10543. Multiple schools (kids) and shopping establishments exist in this area, and the lack of 5G service often means next to no actual service or bars for phone users here. Hoping someone can suggest how to get Verizon to address?
