Bad service

So I called vodacom to blacklist my ****** phone the consultant who mentioned her name as Lona or Lola or something not only couldn't help me also was rude playful and decided to hang up on me as I was still explaining that I need written proof of her not helping me ,so now my phone is lost and chances are that insurance will not pay or replace because of 24hours rule so now I'll have to suffer because of vodacom incompetence.
