Hi Liz, That is the best thing to do, any thing that you are unsure of, the best thing to do is hang up.
If it is a company calling you they will call back,
If still unsure ask for the transaction details date and time of the purchase name of the person handling the transaction and sale.
You are also contact your bank or PayPal for details of the transaction and payment you can find them most helpful once you explain you position.
I hope this helps

If the number isn’t in your contact list the best thing to do is ignore the call Don’t answer If it’s a genuine call they will leave a message 99.9 percent they hang up and don’t leave one Can simply delete Saves a lot of time and hassle
