unfair treatment

My name is Salamina, cell number *** on the 10th of january 2022 at 08:26 i called the call centre to have my tariff changed to my previous tariff before the phone upgrade in september which the call centre consultant assuredme this was done and penalty waived come the 1st of february 2022 i see this was not done i then called the call centre which i was shocked to hear that this was on their record but not processed due to the waiver/penalty i was then referred to a manager Chantel Giannks who assured me my query would be handled accordingly i requested them to listen in to my call on the 10th to confirm this and to date nothing is being done when i called back a few days later i was told that the tarff change was logged but has penatly or whatever fee they call and my incident was closed i never heard back from chantel or the call centre agent that took my call on the 1st with the findings of my query i was promised something on the 10/01/2020 which vodacom is refusing to provide to me i have been their loyal customer for years to be treated as such why is no one at vodacom is refusing to listen in to my call on the 10/01/2022, i even got sms confirmation that my tariff was changed hope this seriously get someone from this company to investigate this further and afford me what was promised
