TELKOM misleading consumers

TELKOM misleading consumers. I upgraded my contract & received a new router(free of charge) in June 2017, was then called in June 2017, was called between March & April 2018to enlarge data bundle on existing contract period. Now I pay for device cost while no device was delivered and the contract period was extended without my consent. I insist on a copy of the voice recording of the latest "UPGRADE" on my LTE contract.
