Refunding my money back

Hi hello peter

I purchase an item specifically a laptop power supply on the 20th and made the payment via fast pay and my account was debited on my side but on takealot side it showed that I ddnt make the payment.. So the order was not paid and after 72 hours it was cancelled due to no payment made.. I phones 4 times and they requested me to send a proof of payment which I did.. They told me that they will escalate the case to fast pay.. I did a follow up but nothing happened .. I even did a fellow up today too and spoke to a guy named sizakele he gave me another reference for the call. which is Ref ***3..but he told me he will get back to me but only to send me an email of the same details send to me preciously saying they will escalate and get back to me.. If I have send them proof of payment how difficult isn't to allocate the funds and repay me.. Please intervine..
