The PSNI has issued a warning to O2 customers in Northern Ireland who are seeking compensation for the widespread O2 network outage problems on Thursday.
The warning concerns a message that has been shared thousands of times on social media.
The message advises O2 customers affected by Thursday's network outage to telephone a number and they will receive a refund.
"Apparently there is something circulating on social media advising O2 customers to ring 141999 to get a refund after the data issues yesterday," said the PSNI.
"This is a prank and will put you through to the emergency operator, please don’t ring it."
