From my understanding, you called UM CS and CS asked OTP, right? What's wrong to just give OTP to them, you are the one calling them.
With the OTP they can skipped to ask more private questions for your identify verification. Btw, Maxis also do that.

I think due to privacy, they need to key in the OTP sent to you to access more private details and to make sure nobody but the number owner authorised the transaction. In their system might can terminate your line if you asked to. Later any agent can terminate your contacted line. Who want to pay that early termination fee?
