charged 5 times for elec

For a few months now I have had nothing but trouble when trying to purchase elec via their website or application. Today I tried purchasing elec again and it declined everytime saying \Technical error. Try again later."Which I did 5 times. I called th en to report the error and they said it's not them it's the provider. I decided to call the Internet banking division just to make sure this has not gone off my account. They confirmed this. I then made double sure and called the credit card division. They then told me it went off 5 times. SO I AM NOW R2500 LESS IN MY ACCOUNT. NO ELEC AND NO VOUCHER NUMBERS!!! THIS BETTER BE REVERSED ASAP. I WANTED ONLY R500 ELEC AND YOUR WEBSITE TOLD ME REPEATEDLY \""TECHNICAL ERROR. TRY AGAIN LATER\"" """
