BBG COMMUNICATIONS are overcharging credit cards for telephone services and HEATHROW AIRPORT is receiving commission for allowing them to continue.
There are endless complaints on GOOGLE, BBG COMMUNICATIONS and nothing seems to be stopping them.

In my case, on the 3rd November 2010 I was charged 60 pounds for three local phone calls. The advertising signs on the phone booths are saying 60p for ten minuets but there is nothing to suggest that Credit Card use involves extra charges and certainly nothing to suggest that I was going to be charged 60 pounds for what I assumed would be a 1.80 GBP charge.
As a pensioner, 60 pounds is an extremely large amount to be robbed of. I contacted Heathrow police who informed me that it was a civil matter and there was nothing they could do.

From BBG COMMUNICATIONS website it would appear that Heathrow Airport are receiving commission for allowing this scam to continue and are therefore in league with these thieves.
From a little web reserch I find that BBG COMMUNICATIONS is owned by a mexican drug lord in Tijuan, Making Heathrow Airport in business with a drug barron.

It is a disgusting Credit Card Scam on unwary travelers and in my case a poor pensioner and must be stopped.
