very unhappy customer

i'm very disappointed and frustrated with Telkom service. it's been 2 months now that i'm receiving incorrect billings. i have been calling and making follow up to no help. on the 10th of Nov 2025 i made a follow as nothing was done or corrected since Sept 2025 (my initial requested for correct billing), i was advised by their agent to rather reverse the incorrect billing that was done Oct 2025- then request correct amount to be billed. i did that, but then nothing was update till to date. Now my account is suspended and i was told it has been handed over to collection. to make it worse, collections they also debited incorrected amount which is now lower than what was excepted.
