Missing application

I app**** online for Telkom's December 2018 LTE deal on 30 Dec. Received SMS the same day to say application is pre-approved & agent will contact me to conclude. By 2nd week of Jan no one has phoned me. Followed up with 180 and 10213. Was told by both I have to request call back from online department. Online dept referred me back to 10213, who in turn referred me back to online dept. Chatted online with latter who eventually informed me that they have no record of my application and just left the matter there without offering any assistance.
