Poor Nimble

I have complained here previously and I have had numerous talks to Nimble to explain that I believe their client is in the wrong but after two years or more of getting bombarded buy Nimble I decided to pay on the information they gave me. The amount was not worth the fight anymore. Now I have paid, sent to proof twice. I asked Nimble and their client to please confirm that payment has been received now I am being bombarded with emails that I have not paid. Poor
