Several newsagents have told me this week of calls they have received from someone saying there is an issue with phone cards or some other product from their business. They ask to be logged into the computer in the business to fix the issue.
Do not agree to this. It is a scam.
Verify the identify of anyone asking to log into your computer. This is easy to do. Ask for their phone number and say you will call them back. Most will drop off at this point.
Please, tell everyone working in your business. The cost if the scammer getting through could be tens of thousands of dollars.
