Def check everything you have there..

When we were renting, we were told that we were 3 weeks behind in our rent (we were normally 2 weeks ahead, so that would have meant us not paying for 5 weeks )..

Anyhow, they hadn't processed some of our payments and were sitting in an unallocated fund account (with our details clearly showing as the payer).

I find they often only look at the info in front of them, without checking other options even when you dispute it..
