Caller id says 'bank card relief', which is accurate! These criminals will relieve your bank card of all available credit, if they get the opportunity! They are to be avoided totally.
Get a call blocker machine--Sentry from E-Bay. They cost about $40.00 and will block 999 calls. They are guaranteed to work on any phone line or your money refunded. When they call hit the block button. From then on the phone will only ring once. You can't block them until they call. The directions are pretty clear and it works great.
