Telkom bad company ever

Telkom Mobile Just like to make money out of people hard earned money and they have worse customer services ever, i have never experience consultants who do not really care about the customer even if you ask to speak to a supervisor they will keep you on-hold until you hangup. Telkom Mobile charge customer rejection fee that is not even on their contract i have asked telkom to change payment method from debit to cash payment each and every month due to i was still out of my job for a while they said they cant stop the debit i had to understand but how do you change a customer a rejection fee that you did not even state on customer contract Telkom Mobile do not really care about their customer they just want to see their customer in deep debt so that they can blacklist them.
