Telkom incoming mail server failures - again

Why is it that Telkom seems unable to provide an ongoing, stable, fault free email service whereby its customers can reliably receive their incoming emails without such frequent server failures. And when this happens the time it takes to get through to them to enquire what the problem is is unacceptable. For Pete's sake Telkom, sort this issue out once and for all; it's been going on for years! And while you're at it, and since you have every Telkom customer's email and cell phone number, wouldn't it be appropriate and customer orientated to institute mass text or email messaging to your clients telling them about system faults and when we can expect them to be fixed? Well???
