Thanks for your post and welcome to the forums. It's really great having you on board with us in the Community.
I'm sorry to hear that you are having a few issues with receiving spam messages. Make sure you are reporting these to Action Fraud UK so they can get as much information as possible to close the scammer down.
Keep blocking the numbers and be sure not to click on any links within the messages themselves.
Apologies that there is nothing more we can do on this.
