Watch out for phone callers who are so dumb they actually use a repayable phone number.
Had 2 so far ,
1. from Amazon claiming I needed to pay for my platinum subscription of $99.99 , problem is I don't have a subscription to renew , idiots.
2. From PayPal to update my payment details. This is only ever notified by email not phone calls.
Both times I kept them talking while taking a screen shot of the telephone numbers and location, then emailed them to the respective organisation.
