A Google Play customer service phone number (1-855-466-4438) is provided in the Android App Store terms of service. However, recent Google Play reviews indicate that the number does not go through.
For instance, in review #2903839, the customer was frustrated that they couldn't call Google Play help because they no longer offer telephone service due to Covid. This complaint often resonates in many other similar reviews. Consumers often reported that they can't get through to a live person when dialing the Google Play phone number.
With that said, there is no other Google Play phone number provided both on the app and www.play.google.com that customers could use as an alternative. As many consumers note, when having an issue with the store, you can try to use the Google Play Help Center instead of calling.
