(510) 509-1510 was a Vehicle Warranty Scam
People have said this is a scam but they didn't ask for money or anything so I don't think so. It sounds like they're actually just trying to reach out to get kids to join the team. There was a voicemail left by Coach Williams that said: "Hey this coach Williams here with Nortel club basketball. I got your number from the local basketball program and was told that you might be interested in playing AAU basketball. Our Spring season is actually starting up in a couple weeks here in April and we are welcoming kids of all ages and skill sets to come and plan our team. So we would love to reach out to come check us out. If you're."
