calling on someone else personal phone requesting to speak to me

Good day

Today I feel so disgusted with Capitec how can you phone on someone else cell number looking for me, I always you guys cause, I love ur app and services, but today call on someone else phone is not on really how can you call on someone else phone requesting to speak to me my banking business is my private mater I do have a landline at work and I surely assume it is on my banking profile, I feel as my privacy was invaded, what if the lady that spoke to the person who called said she was me really, this is not on. when i wanted to give my number to call the line was cut.
