Thank you for your reply! I was jut worried as I had no proof of the payment as it was years ago!

Hi, back in 2010 I took a payday loan out with quick quid. I struggled with payment but I finally was able to pay the full amount back in 2012, today I received 4 automated phone calls from MMF about a urgent message so I obviously rang them back to find that they are telling me I owe them money for quick quid?! I haven't received any letters, only 1 email saying to get in touch with them about a overdue payment!i didn't pay them anything but I'm worried now. Can anybody give me advice please? Thanks in advance!
