VODACOM BAD SERVICE

Once again impossible to contact Vodacom from overseas. You promise to call but don't understand that if roaming not switched on then we cannot receive a call. First problem resoved by cancelling debit order...then there was an email. I rep**** and received a reply. I try again with the same e-mail address and reference number NO REPLY. Resent e-mail 3 days running. Vodacom your service when one is overseas is absolutely atrocious and if I could give negative stars I would. TOBI is worse than useless and you have no other way to contact you except by posting on here. Jack up your service please and at least have a customer service e-mail address.
