Who called from 2814034003

got a text from a different number saying to call HSBC at this 281 number.  I've never had an account with HSBC.  I called the number listed on the HSBC website and they have no record of an account for me.

The same this just happened to me. The txt was marked "Unverified-Sender" and read (exactly as shown):
(9178138459) H/S/B/C Update. Call 2 8 1 4 0 3 4 0 0 3

I do not have an account with HSBC and I call the number and they want me to enter my account number.  They keep texting me!@!!!

When u called did it say it was Actually hsbc?

I tried sending "stop" to this number and it keeps sending it to me. Same thing - HSBC. in a text message
