Bad Service

I ordereda book from takealot on the 03/07/2015 and made a payment the very same day at 13:00pm and when I called to track my delivery on the 07/07/2015 I was told that I did not make the payment, I then went to the bank to withdraw the bank statement and sent it to them via the email 3 times and to my suprise I was told that the attachment is not a pdf but when I sent it it was on a pdf format and even faxed it to the to their fax line but I am not getting any assistance and now its frustrating as my studies are now on hold as they are taking me back and forth. I used the correct banking details and the reference used was the correct one but to my suprise is it that difficult to withdraw a bank statement and do a reconcilliation?definately my payment appears on the suspense accounts
