Sometimes I just get pissed enough - not to answer but to call back - which I did with #67 so they could not see who was calling - told him what a scammer he was and he sould learn to speak English - he told me to go to hell and I said you also.
Didn't answer, but they left an automated voicemail claiming to be from "apple support". Checked the phone # on 411.com and it had a "heavy spam activity suspected" banner.
They leave a voicemail telling you not to use your Apple device until you call a certified technician at 1-800-815-5126. This is a scam. They are either trying to get you to download software (spyware or malware at best) or phishing for your iCloud ID and password. Scammers.
