bad service from gaba mosuoe

I as the unhappy customer, Gaba Mosuoe refuse to lock my number as I requested her to do that. I'm not happy because the lady didn't do as I requested, the number in question is ***, who's number is this if she didn't want to do as I requested, me the account holder, I think she deserves to rot in hell, she can't work with customers and she's so rude that I'm not sure if she knows her duties at work
