VERY VERY UNHAPPY

I recently moved my cel contract from my pvt acc to my business acc. I have been a client for more than 20 years and have had a vodamail acc since I can remember. VODACOM / VODAMAIL decided to de-activate my account and now all my emails that I have saved over the last 20 years is missing, Gone and apparantly cannot be retrieved again. HOW DO THEY JUST DE-ACTIVATE AN ACCOUNT. Gilchrist, Marianne from Vodacom seems to think sending me the T&C's are a solution. THIS IS NOT THE WAY YOU TREAT CLIENTS. How can you offer your clients an email acc and then just not have any kind of backup when YOU decide to de-activate the account without permission or some kind of written notice that he account be de-activated. I never cancelled my contract, I just moved it to a different name.. HOW DO I RETRIEVE 20 YEARS WORTH OF SAVED EMAILS
