Commenting in response to Ofcom’s decision to fine GiffGaff £1.4million Ernest Doku, mobiles expert at uSwitch.com, says: “Giffgaff users will be concerned to learn that 2.6 million customers were overcharged by almost £2.9million.
“Anyone who bought the firm’s ‘goodybag’ bundles of calls, messages and data while using pre-paid credit was unfortunately billed twice every time they used their phone.
“Giffgaff deserves credit for reporting the mistake to industry watchdog Ofcom and acting quickly to refund 2.1 million customers. But the fact that almost half a million consumers are still out of pocket is disappointing.
“If you are a Giffgaff customer and believe you could have been overcharged, contact your provider as soon as possible.
“The size of Giffgaff’s fine represents how seriously the watchdog takes this error. And providers be warned: mobile phone users will be quick to vote with their feet if they believe they are being treated unfairly.”
