1-Grid customer service is non-existent

1-Grid is our companies e-amil host. We have in recent months experienced frequent problems with our email not working. The most recent incident left me speechless. I stopped receiving emails and shortly after was unable to send any emails. I attempted to lodge a ticket on their website, but to no avail. As a last resort I called their customer care line. I have now been on phone, rather on hold, for the past three days using up no less than R200 worth of airtime. The hold time is approximately 40min before the lune just drops. When selecting the sales or billing options they are quick to answer, only to again place you on hold for the support center. As I am typing this, I have already spoken to three separate people in the billing department and my current hold time is 37min and is still ongoing. This company has no interest in assisting their customers and has yet to resolve my issue. Not being able to use my email has been detrimental to our small company.
