Lack of service/Over charging me for services not received

The worst customer service experience ever.

I had cancelled my services back in May. I gave a months notice and router was collected in the last month of service around the 18th. I didnt mind that they collected it earlier. I was on a 30/30 gig night and day data bundle which I normally paid R250 for every month.

I then app**** again for services August and I noticed I was charged R250 in June and I cancelled my services.

I have been calling Supersonic every time and all they say they are investigating my account.

What are you investigating??

I started in August and did not even receive services for 15 days because my account shows in arrears of R250 which I have cancelled my services already.

My account was still deducted the full amount for both months and the extra R250. Up until now my speeds are ridiculous and could not use the router properly and im being overcharged.

This is unacceptable.

I would never recommend Supersonic to anyone. your service stinks.
