POOR SERVICE

Have being trying to resolve a query regarding non receipt of emailed statements and invoices for three months now. I have emailed "customer care "and "complaints" in this regard. To date no communications whatsoever from them. There appears to be an issue with emails from MTN not being received by me ,but according to the Help desk they only communicate via email and cannot be contacted by phone. How does this help me if I am not receiving their emails.
