Poorest customer service

I am so ****ed, I bought R150 worth of airtime recharged using the telkom app for my pocket router. Unfortunately i missed a number I contacted them immediately after i realised the agent was utterly rude,she said why did you recharge an incorrect number as if i did it in purpose...after an arguement she said it was escalated that was on the 6th November she said within 24hrs, i waited then decided to check using their chat service i found another rude person ask for superior but did'nt come back to me not that i had not even received any reference! I went back to their chat service later on the 7th a kind lady assisted me and i even received an sms with a reference she said it takes 72hrs,i waited yesterday i spoke to Samantha from their chat service she also told me about another 72hrs,I requested a supervisor which i spoke to i think he goes by the name of Rodney he said he will transfer the airtime to me before the end of yesterday and give me a call back. But he did the same thing he did not bother coming back to me it shows that it is their culture to make fools of customer i am really disgusted
