The Dish Network is a popular satellite television and Internet provider used by millions of people, which is why it is a good hook for scammers who are calling people purporting to be Dish Network technicians and telling their intended victims that their equipment is being updated and that a technician would be coming out in a few days to complete the upgrade at a cost of $200, a charge that must be paid immediately.  In many instances the calls appear on Caller ID to have originated at the Dish Network, but that is not true.  The Caller ID has been manipulated by the scammer to make it appear that the call is legitimate.  In many instances, the scammers actually have had the customer’s account number or even the last four digits of the customer’s credit card.
You can never be sure who is really calling you on the phone which is why you should always be skeptical if someone demands money or personal information under any circumstances.  In this case, the Dish Network does not call its customers if it is upgrading their services and they do not charge for upgrades.  Any notices from the Dish Network would come by regular mail or email.  If you receive a call that you think may be from the Dish Network, you should hang up and call the Dish Network at a telephone number that you get from your bill.
