Hello I have been advised by my mobile tel provider that since I visited USA in October 2014 that I have been billed for services re bundles that I did not request or authorise. This went on for a period of over 12 months and only ended in December 2015 when my mobile phone was changed and a review of my account and costs was completed. I have rang opera telecom on four occasions now and been told that someone would ring me right back but this has never happened. I would now like to make an official complaint and be refunded all of the money which was approx £7 per month x by 15 months. Many thanks from Sarah fitzsimons tel [protected]
