Expert Opinion
Beware of persistent calls claiming to be from O2. Many users report the same number repeatedly offering upgrades or tariff changes, often without confirming the caller’s identity. These calls can feel aggressive and may be part of a third‑party marketing operation rather than the genuine network. If you receive such a call, hang up and verify directly with O2 using an official contact number. Register the number on the Do Not Call list, block it on your handset and report suspicious activity to your provider. Avoid sharing personal details until you’re certain the call is legitimate.

I dont need whoever is calling, they can just leave me alown, I'm not intrested.
Since mid-February, I've gotten 5 calls claiming to be from O2 Sales, including 3 over the weekend, but the number isnt verifiable so I've blocked and marked it as harrasment.
I'm getting constant calls from 02, they wont stop and its very anoying, i'm thinking of changing my provider now
