Worst customer service I know

Just when I thought their customer service couldn't get any worse after taking more than a month to relocate my fibre connection to my new home... I was shocked to see that I was charged for service at 2 residences in March - the old residence which I left on February 1st which was supposed to be canceled, and the new residence where I live!

On top of that, they always say "I've logged a case with our X department" but they never follow up to let you know the progress of the case. One customer service rep told me recently (I don't remember what day because I have called Supersonic so many times) that they would call me back the next day. Do you think I got a call back? I'm still waiting to find out if I am going to get my money back and when for the double charge.

One of the traits of good customer service is keeping customers updated and letting them know when something has been taken care of. This company is the worst I've experienced in South Africa in this department.
