Telkom bad *********** service center (s)

My current 100 Gig LTE data package is not enough. I want to downgrade the LTE to 40 Gig and add Telkom fiber to my account. Nobody can help to tell me what the penalty fee are to downgrade or migrate to telkom fibre. I went to the telkom store in Cresta. I was told to phone 081180, they told me to phone 10213; they told me to phone 10210; they told me to phone ********** 500; they told me to phone 081180....The operator had me on hold for 21 minutes talking to her manager and was then transferred to the technical department......I am not happy. Is my request really so difficult..... I will not recommend anybody to use telkom or even try their support/help services. I even went to the telkom community chat, not good and people are upset.
