Apple Watch not connecting

[Gazzah]

Bought an iPhone 14 pro max and series Watch 8. 
the Watch will not connect to cellular data been trying to sort it for 3 weeks. No help at all from calling 202 and no help from in store. Been promised a manager call back 3 times each time to wait 72 hours.  They sent an esim apparently that’s not correct can someone help with connecting my Watch to the data?

Hi @Gazzah - with the temporary cessation of O2 Forum Advisor service here this past week, the only thing I can suggest is to contact O2 via Social Media, the details for Twitter, Facebook and Instagram are in the link just below this post. 

Let them know the issue, briefly, and they will probably ask for more info via Direct or Private massaging on the platform.  You can keep an eye on progress using that conversation thread until you get a resolution, @Gazzah - best we can do, as we are all customers here as well, and cannot access your account. Good luck!
