As someone working for a telco, not Vodafone, this would be my assumptions: A developer mistakenly grabbed a real MSISDN, instead of a QA one, while testing a promo still in development.
I only say this because there's no identifier to differenciate a real phone number from a test one. Subscribers often called to report those gibberish text messages they received. It's always a dev entering an incorrect number while testing.
