******** NETWORK PROVIDER TELKOM ?

Yesterday I bought R155 air time to buy the LTE data of R149. But it didn't allow me. ( I DON'T UNDERSTAND WHY IS THAT FIRSTLY??) today I just bought R5 to add to make it R60 on it but now I have only R5 air time how is that ? possible? *** I only use this Sim for my router I ddnt even make a call but the airtime is gone how?? Am very angry at this moment because I used my last to buy airt and data but now I have no date on the Sim and no airtime WHY AND HOW?, ????
