It’s not surprising that O2 have a 1.5 rating out of 5, based on customer experiences. The message is: Buyer beware! Their customer service in my opinion is totally shambolic when it comes to switching contracts...from Business to Personal (x2). It all began five months ago and is still ongoing... Yesterday, another demand letter arrived to pay off my original Business Account amount, which was closed on the 6 January 2023. An outstanding payment was made early ‘23 to settle the ‘Business’ account and as far as I am concerned was the ‘final’ payment. But, because of their latest aggressive, threatening letter and a subsequent ‘phone call to two Customer Service Agents I, again, decided to pay this off, on the understanding that this would be the ‘genuine final payment’, and this fact was confirmed by the Agent, whose name is now on my records...just in case! (Thinks! I still have my doubts...) For the reader’s information, over a period of five months, I have visited my nearest O2 shop on several occasions to resolve with little effect, made several ‘phone calls to a regional O2 hub, and many lengthy ‘phone calls (including long waiting times!) to achieve contact communication with a Service Agent via tel. No. 0800 977 7337. Incidentally, many of the excuses for their poor service was blamed on O2’s Computer systems and software, including upgrading! So, hopefully, no more demand letters, or bad customer service...and, from a personal point of view, no more time consuming visits, ‘phone calls and further stress! Watch this space...
