vodacom is so hell bent

vodacom is so hell bent, so dishonest in dealing with clients. they say i should pay them, i told them i don't mind paying but the amount they are asking me to pay can they break it down or explain it to me so i can be clear. i never got a reply, i got an email from Linda Morgan , she asked me to contact her ( 082-146) i have called so many times, i am told she can not come to the phone when i asked for her email no one can give me the email. how are we going to resolve this?
