I have been a loyal personal and business customer with O2 for well over a decade, but my recent experience with their business customer service has been extremely disappointing. As many others have mentioned, the call quality is poor, making it difficult to hear the representative clearly. I had to repeatedly ask them to repeat themselves, which was frustrating. To make matters worse, the representative was required to go through an upsell script, despite the fact that my issue had not yet been properly addressed. This felt more like a sales call than genuine customer support. This experience alone almost made me consider leaving O2 entirely. I expect better service from a company I’ve been with for so long.
