Said they were calling from Worldpay and wanted to know about our card machine. We were previously with Worldpay so it should have been on their records.

Vonage Limited operates as a global cloud communications provider owned by Ericsson. The caller was trying to find out which card machine provider we use so he could offer a better price. I have told them I'm not interested. But they still called twice a week.
Reported caller:
Vonage Limited, card machine provider

Called place of work. Asked to speak to 'Harry', to which I responded that no one by that name works for our company. Caller then asked what card machine we use, to which I responded we don't have a card machine. He asked what about card-paying customers, I then hung up as obviously they have no knowledge of our business and felt uncomfortable providing any further information to an unknown source.
