I just got it too. It's a scam. Call the police and report that number. When you call, they ask you to enter your credit card #. So they are trying to get credit card numbers.
I just recieved the same text from 9099 saying "customer issue, california credit union service frozen" it's a phishing expedition. Do not Call.
Details on the number; number points to a Royal Oak, Michigan number. OCN 9323 Ameritech Michican, LATA 340. CLLI code RYLOMIMNDS0
If you call, they will ask you to enter a credit card number;
