Charged for content subscription and upgrade without permission

I have been with Telkom contract for more then 14 years and I had a great experience

Recently I got charged for content services subscriptions, that I have never joined on my side

The first month I brought it to thier attention and they promised to refund me after investigation and they removed them

Second month I got extra charged again and reported it to them

Still no refund for the previous and even the new bill

The payment did not go through because the amount was less

Come this month,I was chard for late payment

I feel this is unacceptable because I got charged twice in a month but they could reverse my money but have the guts to charge me for something that was caused on their side

I was changed to another contract without my permission and changed for upgrades

Telkom costumer service is bad including their walk-ins

I am frustrated with anger
