Consultant Attitude/Info

This was probably the worst service I have received. I have been a client since Feb 2016. Paying each month and truly not having any issues with the provider,until today when I stopped my account. Finding ourselves in the current situation and being at home, not needing my mobile data bundle top-up. After finally speaking to a consultant and stopping my account I requested a confirmation e-mail stating that this has in fact been done I was put on hold again. After another long holding time I subsequently dialed again hand was then helped to confirm that this was in fact completed. My issue is with the attitude of the the consultants and not giving information as to why a person is placed on hold. I understand the "high"volume issue but still, at least give some info.
