Bad client service

I tried future dating a payment - but there was an error and it didn't allow it. So I checked the payment history for the recipient (to make sure) and saw that the transaction definitely didn't go through. I then paid the recipient immediately (which worked great). But now - there are 2 transactions. This doesn't make sense. I tried the live chat option - but absolutely no help (this is not the first time). I just want to close my account at this point.
