Complaint

I made payment to the Etoll at the grove to top up my account of an amount of 250,the amount was taken from my account but my Etoll wasn't toped up because they were offline,I was told the money will be resent to my account because of the situation,I'm here for the 3rd time,no assistance has been provided and still waiting.I was told to get a bank statement to show proof of payment and they claim that the proof is vague and it's quite evident that the money has been subtracted,really upset by the service I'm receiving from this branch
