Who called from 4165552121

I receive unwanted text messages from this number several times a week. Text is all garbled. Return calls to the number advise "your call can not be completed as dialed"

I recieved two texts in a row. It was all nonsense letters, upper and lowercase, and numbers and symbols mixed together. Stupid.
