is it ok for an employee from chase to get your personal number and text you?

Since you don't mention any kind of underhanded way by which the employee got your number, presumably you had provided that number to the bank, and/or it was publicly available.  You also don't mention any restrictions you had placed on the use of that number, for example telling the bank that they could not text you.  Nor do you mention anything objectionable about content of the text, i.e. you don't say that it was threatening or sexually harassing.  Assuming all of the above to be true, I see nothing wrong with the bank employee texting you about business you had with the bank.
