Telkom has terrible communication service

I am quite disappointed with the service Telkom has rendered. I app**** for Fibre in March of this year already as I am currently using LTE, my application was processed and i was told that installation would only happen in June, it's now July 28th 2021 and i have received no communication as to what is happening and when I will be able to switch to Fibre. I have tried to contact the sales agent, but no success. Iv been telkom customer for 2 years, I dont know why the service is so terrible, any form of communication with customers is acceptable but no communication is terrible service.
