Terrible unhelpful customer service. Total waste of my time of 30 minutes ! ! Asked two simple questions only. 1. How much data for EU left out of 25G? (not the general total data amount which I can easily see in my online account) 2. Why is the extra charge shown in my O2 online account which will be deducted from my bank next week? Simply answered to accept extra money taken out from my bank account first and then try to contact them at that time again to ask why ! ! And they can’t see EU data allowance left in my account. I need to know before I go EU again !
