These gronks keep calling from similar phone numbers with a recorded message saying l have been billed some amount for Amazon membership. If l want to clear it up to push whatever number button. I keep ignoring and blocking all calls with the prefix 9067, but they just keep changing the last few digits. Occasionally, just for a laugh l press the 1 key and randomly say hello into the phone every 20 seconds or so to keep them interested. BLOCK AND REPORT!!!
