EE customers to share £1m refund after VAT kerfuffle
The EE customers were those who went outside of the EU and used internet data between October 2012 and October 2014 are affected - about 0.5% of EE's total customers.
EE told the BBC that the cash was never EE's and that the overcharges went straight to Revenue & Customs. Customers affected can expected refunds from about £2 to £80 per customer.
Spokesman David Nieberg said: "Due to a configuration error in our billing system, made following a system change, a small number of customers were wrongly charged VAT on the Data Roaming bundle outside of Europe."
"This was a mistake, and we are now refunding these charges and contacting affected customers to apologise for the error."
He added: "We've claimed that money back from HMRC, and then it goes back to the customers."
Customers affected by the error are being contacted via text message and told the amount they are owed, and any former customers who believe they may be eligible have been told to contact customer services.
