Highly disappointed

I called the call centre to inquire about my bill . Telkom for some reason the app doesn’t work the number to dial the billing department does not work .I got through several agents and for some reason the last agent was extremely rude spoke over me did not understand what was my issue’I can’t understand how telkom does business with such ********* ways. Is this how you treat customers who are paying almost 2k a month for a contract .I am very very very disappointed makes me never wanna do business with such *********** people ..
