Reversal

I recently did an online shopping not realizing that I click on the wrong website..I contacted Capitec bank to assist in a reversal and I was told I should report in 30 days my question is how will you reach or get the money back in 30days what if the other account now won't have the funds for my reversal am really disappointed with capitec Bank..I tried to also get assistance on other products they provide/offer and they gave me a long story because the pay slip was In foreign currency and commission based and was told that they couldn't help me because of that ..I've been a customer for over 10 years but this bank can really disappoint
