I have exactly the same issue, endless calls and messages looking for "amy huckerby" if anyone knows her, can they tell her loan has been approved even with her bad credit!
It's so annoying, I've had the phone number since my first mobile - 14 odd years ago and that is the only solution o2 can offer
I am currently getting around 40+ messages a day, and at least 15-20 phone calls, my phone is practically unusable for most of the day. I am registered with tps, and have been for years - I have also tried some of the spam blocking apps from the play store, but some still slip through and with current andriod you can only have one sms app so you end up with terrible messaging apps!
with the volume I am getting forwarding to 7726 isn't really an option, especially since you have to send it, and then send another to confirm the number it came from - it would be good if there was a way to upload/send them all at once.
