Abysmal online service

Clicks' online service is the poorest I've ever come onto contact with. It's been over a month that I'm still waiting for a refund that is owed to me due to an error on their side. Trying to get hold of them via email is a waste of time. Calling the call centre you're on hold for over 10 minutes at a time. And don't even try getting hold of anybody in a managerial position because you'll be on hold until your airtime is finished. Imagine being told 17-20 working days for a refund!!! And then when the 20 days is up to be told to wait another week with no explanation provided.
