Vodafone Unwanted Messages from +44 Numbers

My Vodafone GSM number is constantly giving me trouble. Despite repeatedly blocking them, I continue to receive messages claiming I've won prizes from numbers beginning with +44. These constant messages irritate me greatly, and I want them to stop immediately. It's perplexing that the messages continue even after blocking these +44 numbers. I'd like to emphasize that I have no desire to receive messages from any +44 number. This situation is not only bothersome, but it also interferes with my daily life. I implore Vodafone to act quickly and completely block these unwanted messages from my number. As a loyal customer, I believe I have the right to control the messages I receive. This issue's prompt resolution is greatly appreciated.
