I would give zero if that was an option. I have had terrible experience with aO2 and they’re none existent customer service, After. 2 hour call and 7 different operators they finally cut me off without resolving my problem. The operators clearly didn’t understand me and passed me onto another. After 20years of being a loyal customer the way I have been treated and left out of pocket I am now switching to another provider. Awful and appalling customer service
