I am GATVOL about people who do not listen to customers!

I have been in contact with Telkom to upgrade my WiFi and convert my personal number to prepaid since I bought a new phone already. To my surprise the old debit order was combined with the new one and the amount went exponentially high. I am so disappointed because I've been in contact with them several times. They don't LISTEN! I'll cancel everything and look for a listening institution.
