Received a call from them, it went to voicemail and they didn't leave a message. I tried to call back and there was an american female voice on their voicemail saying "This number is not in service".

Called hung up when i answered, called them back not in service, called back and talked jibberish indian and hung up

They called and left message. When I called messages there was no message. Just lots of people talking in the background. Have blocked number
