Telkom *****ing my airtime

Ive been having an ongoing airtime balance issue we're the amount of airtime I purchase deplets quickly and when I check my balance I still have airtime but can't make calls or smss.....Telkom is somehow *****ing the difference in airtime... I called Telkom We service and carried out all the necessary checks to like restarting my phone and the problem still persists....I reported this issue in October and spoke to one of their college's Thipe Thulare , I gave him my simcard Iccid number and other necessary information but to till this day he hasn't gotten back to me and doesn't respond to emails...he told me I would get a reference number sent to my phone but till this day I haven't received anything, and evertime I do report an issue with telkom I never get this reference number sent to me, which means nothing was or actually being done.....im very disappointed in telkom, they are quick and responsive to sign you up for contracts but are slow and lazy to assist you with problems....Nomore
