I want my data

Am really irritated with the way Telkom do things,on the 31 December I loaded data on my phone and received a message that my data was loaded successfully but when I checked my balance I had no data,I have been trying to call Telkom on all their customer care numbers I know but I can't get through to someone to assist me, this is really unprofessional, all these numbers when you call them you get an automated answering machine but you don't get to speak to the agent to assist you,today I had to load another data and fortunately I had no problems but I still want my data that I bought on 31 December.
