MTN braindead

I have been trying to get invoice e-mailed to me for over 6 months, despite calling every month. Finally I get message below lettinge know it's been sent. You would think MTN would be smart enough to know an email needs a @ sign and not *. No wonder they so useless.essage I received below Y'ello. We've sent your monthly statement and tax invoice for account BA*** to tony.rall*trevally.co.za. MTN Team.
