Telkom Bad Service

I am so frustrated by Telkom. 😭😭😭😭 They debited money for my cellphone contract, only to tell me now that the payment they debited did not get to them, saying I reversed it. And that isn’t true. I even submitted my bank statement to show that money did leave my account and it wasn’t reversed, they told me they still investigating. 7 days has passed and still no response from them. My phone is blocked. I cannot work. I tried to go to the bank today to have that money reversed so I can pay it manually but at the bank they told me, they cannot reverse it as 40 days has passed. I don’t know what to do now. Telkom isn’t helping me and they took my money. They telling me to pay but how do I pay twice?
