Thank you thank you thank you to both Ayesha and Chegan. I'm SO grateful for their help. This would be 5 star review but unfortunately I had to call twice and wait on hold for a long time to resolve my issue, but other than that the service was fantastic. I had a nightmare with phone charges from Qatar Airways, no fault of O2 at all, but the advisors were friendly, kind, compassionate and happy to help me. I'm so glad and relieved that good customer service still exists. Can't say how thankful I am.
