I had 3 accounts with O2 (over 15 years with O2) and now moved onto another company as I paid £600 in total for bills between July til September for driving in Europe and non- Europe countries! I didn’t deserve to be charged so much for just driving through a country. I wasn’t even aware of these charges.. I was promised a refund of £75 each (for me and for my husband) I received mine but my husband never received his! They advised to call them back on 16/10/20 to receive this refund which I will do. But why have I been treated like this I don’t know! Always been loyal to O2 with 3 of my accounts. I was very very disappointed!
