Bad Service from Telkom

I ordered a fiber line, it was never installed and no router was received, but i was billed. It took a lot of my time to get hold of someone to get a credit. Eventually, I canceled the whole order. This month I get a bill for the router and installation claw back. Really Really frustrating. And now I have to call the billing department and explain the whole story again and then will probably tell the system is offline and they cannot help me as usual.
