Public warned of scam where people called and asked to donate to Metropolitan Fire Service South Australians are warned of a scam where someone is claiming to collect money on behalf of the Metropolitan Fire Service. SOUTH Australians are warned of a scam where someone is claiming to collect money on behalf of the Metropolitan Fire Service. The MFS became aware of the scam on Friday when one of their firefighters received a cold call from a person claiming to be collecting money for South Australian firefighters and asking for credit card details. When the firefighter questioned the caller, they said they were collecting money for "training for firefighters." When told they had called a firefighter, and that neither the MFS or CFS collected money, the caller hung up. An MFS spokeswoman stressed that the MFS and CFS do not call or doorknock the public to collect money, and warned people to be wary of the hoax.
