Escom Prepaid Purchase

After purchasing prepaid electricity via an FNB machine, the amount of R200 was deducted from my account. The machine issued a slip stating Prepaid electricity and amount but no code number for electricity saying had encounted a problem. After phoning the number given for this transaction using all my airtime (R60) they told me to visit FNB. There is only one bank in Memel where I live which is FNB. They contacted STB who then said the transaction went through as airtime(whose NOT mine). They gave me a ref No *** and said a 5day wait. Today 19th Jan is 6 days. After phoning again was told it had been resolved (another R35 airtime). I have not received a refund or code for the prepaid. What the **** is going on?
