Shocking Vodacom Service - or rather non-service!

I have not been able to access my Vodacom e-mails for the last 2 months! The first time I reported it to Vodacom it took about a week to get me back online via a different web site. I had access for about 2 weeks and then no access again. My e-mails remain unanswered and trying to call is a no-go because they are always having "high call volumes"! Why am I not surprised?? They have no problem taking my money via debit order each month but what do I get in return? NOTHING!! I cannot be reached via my e-mail account; only telephonically via ***. I wonder if anyone at Vodacom will take the trouble to contact me??
