Cell c standard bank atm prepaid purchase

Hi I purchased cell c prepaid airtime at the standard bank atm on 25/09/2017 for amount of R400 today is 2/10/2017 I have still not received my airtime purchase when phoning the bank they say it's a problem on cell c side they have reported it to cell c and say it's not their responsibility as a client I dissatisfied they deducted the money same time yet now it becomes a inconvenience to the customer to get what they paid for and giving the customer the run around when it's a service agreement between cell c and standard bank to ensure customer gets what they paid for.
