my conseiller is ignoring me

Hi, could you help please ?

i left France and I wanted to close my bnp account , I don’t have access to my online account as I closed my SIM card ( I need to enter sms code to access it).
Fortunately I had an email of my conseiller (Fatoumata Cisse, Grenoble Echirolles) , I explained her the situation, And she said she will help to close my account through email , but later she just ignored me , and send automated message that she is leaving the job, and someone else will cover her. I tried to call them million times, never answering!!! it’s Expensive international calls.

now I have no idea what to do , could I share my personal info, so that someone will come back to me to close my account?

thank you in advance,
