BAD CLIENT SERVICE WILL BOARD!!!!

I will not be upgrading my contracts this year at VODACOM!!!! Loosing me as a client after so many years. But won't even CARE!!! They changed my username (cell number) on my e-mail profile to my normal daily cell number, as I don't use the other sim anymore, the ********** was then cancelled. I asked the consultant, if they change my profile, will I still be able to access my old e-mail, where by he rep**** YES..... guess what I cant access my old mails, everything was lost.... And Vodacom just pull their shoulders up, Sorry you cant get the old emails back... that is not the solution I want to hear...... they cant reinstate the number as it was already given to a new Vodacom client. This is not the 1st time having trouble with Vodacom..... my prev complaint they didn't even get back to me. BAD SERVICE!!!!
