Don't answer clients!

We have a business account with them and yesterday I got this SMS: Standard Bank: A recipient has been added to your MyUpdates profile.2018-02-14 Query? ********** 107 Only problem is that I haven't been to the bank yesterday or any day before that and last time I was in the bank was about the 29th of Jan!! I queried yesterday on their Facebook wall as I'm sick and can't go into the branch and the person replying there (although I gave the account number) wanted my ID number which I sent in private msg but till now has NEVER responded!! This is becoming the usual thing with this bank!! Its not the 1st time I'm waiting for answers!! If this keeps up I don't see a future at this bank!!
