Telkom call center service from bad to useless.

Upgrade in March 2018, billing charged incorrectly since then, phone the call center, speak to more than 8 persons not able to help as nobody is authorized to help. They can only upgrade you without the discount. The modem and other stuff that was supposed to be delivered within 14 days never arrived. One consultant promise that it will still be delivered. Still nothing. Today I receive a sms that my services is suspended. Only one way communication from TELKOM !! They can do anything and the user nothing. I did pay every month the amount that was advertised. They even reverse a months subscriptions with a debit!!! How stupid can they get. Why do they have a call centre??
