Shocking customer service

After cancelling my account due to poor network coverage - which i declared as the reason for my cancellation, i was subsequently bombarded with agent calls during my work hours trying to get me to answer survey questions to establish why i had cancelled - after i had already given them the information. This bizarrely spoken agent kept calling repeatedly, disturbing my meeting.

I decided to phone and speak to management to complain, only to find that nobody ever picks up the phone at customer care. I requested a callback several times via the website and still nothing. I do not know if they have effectively cancelled my subscription even though i have asked them to do so multiple times and have received no confirmation or client care.

Another example of shocking customer care in SA.
