Email wont go through

I am battling to cancel my cell phone contract for ***

I contacted Vodacom, and after being shunted through various departments I got all the details, made the required payment and now I can't get the email through to Vodacom.

I have called an received several email addresses to which I've sent the mail with all the documentations, but the mail gets returned saying no such address.

I have tried *** And ***

Can I please get the correct address to email this to.

This morning I called again and asked Nomvula for the email address, but she shunted me off to the business call centre mid-sentence.

Can I please just get an email address to send this to and can you simiply your email addresses please.
