Give em hell (888) 514-0972
Can I call this number from Germany ?
Yes, you can. It would probably be better though to get some sort of prepaid US number from apps like: Vyke, RWG Mobile, Cloudsim - they also have kind of cheap rates so you will also pay less without revealing your number. And you can also find more indian scammer numbers and waste their time so they have less time trying to scam other people.
