Charged but still have credit balance from promo code
I am entitled for promo, spent $50 and get $150
I manage to spent my first $50 and receive the $150 as of 21st May 2017.
Currently the balance on my account is -$31.86, which mean that those are the available balance in my account.
question is, i was charged $50.60 today. I am clueless why was i charged when i still have balance on account.
I have calculated my spending from the first $50, until i was given the $150 promo to the current balance of $31.86. it seems to be tally. Im just curious why the charges incurred to me today.
