BT has denied it has cocked up the billing for its Surftime product by overcharging its customers.

Ian Fenn, director of Chopstix Media Limited, claims one of BT's customer service operators admitted to him that the telco had incorrectly charged punters.

"I signed up with BT Surftime when it launched in the middle of June and have only just received by first 'Surftimed' bill.

"The monthly bill came to £154.20 - £30 more than my previous non-Suftime bill," he said.

"I'm told by a BT customer services advisor that they have incorrectly charged Surftime customers for Surftime, plus the cost of the Surftime calls.

"A credit is being applied to all affected accounts, but this won't help those that have ended up in the red due to this particular bill," he said.

Asked about the scale of the problem, a spokesman for the telco said: "I'm not aware of any problems." ®
