Contact center agent giving bad attitude

I called the contact center asking for cross-border letter for my vehicle (*** - ***) and Zunaid picked up the call.

I am really not pleased with the tone and the attitude I received from him. It's not the first time I have requested this letter.

I did mention to him that due network (Coverage) issues in the office I cannot access my computer which meant that I won't be able to send him the letter.

I would really appreciate it if you can actually school him that both letters are required at the border gate in order for the car cross the border.

Regards,
