Vodacom billing

We have sent too many time to the following email for requesting an invoice, however, never reply, your customer service is very very terrible.

we also make a lot of calls to ***, ***,082135, nobody is responsible to help, just transfer to a different department, then let you hear the music, hey, I am not for music.

The email sends to: ***, ***, ***, ***, ***, ***.

You just debit order my money for R19,151.21, but never reply the email for requesting an invoice, that is your woking attitude of your employees.
