I've logged on to my bank account a few hours ago and noticed that the bank transfer I did to her was rejected and returned. I did show her last night that the payment had gone through and I got a completed tick on screen. I also asked her to confirm receipt in her account, she just said "yes OK".
I text her a few hours ago today, saying I've just noticed the Bank Payment didn't go through; the message has been read but I've had no response.
If that's the reason for all of these texts and she knew there was an issue, she could have just sent me a single text.
As it stands I can't pay her because the payment will likely get rejected again.
