User Testimonials for O2 Mobile Support

Helpful and resolved my issue by blocking my phone and reporting it to the fraud department. New SIM card will arrive in a few days.
From Lashayla Aug at 2024-10-18 -
Lengthy hold times and delayed responses despite providing evidence of cleared payments have eroded my trust.
From Becki B Vrp at 2024-04-11 -
Not helpful when contacted; years with them but facing persistent issues.
From Ian C Dav at 2024-05-02 -
Terrible treatment with no response to complaints. Would never return.
From John Hughes at 2024-08-01 -
Polite support, yet clueless and scripted, with communication hindered by thick accents. Poor service now compared to previous experiences.
From Benjamin Pritchard at 2024-10-28 -
Absolutely no idea what they're talking about, an absolute shambles. Consider walking away.
