Settlement agreement confirmation letter

Good day. Consultant contacted me today 1/10/2019 @6pm and we discussed settlement payment. Was given the option to pay in two halves. I just needed a settlement agreement letter via email so that there is proof of our conversation, because when I redial the number, the phone rings forever or someone keeps on dropping the phone. When someone eventually answered I've waited very long for her to take down my email address that I've already supp**** to the gentleman that called me earlier. Just need confirmation letter, it is unfortunate that these days you must have paper trail because it's always the fault of consumer or client if the 'system' can't prove if there was any payment.
