They gave me a good deal

They gave me a good deal. The installation was good and I feel communication could be better between the teams and sub-contractors. I made a payment of the deposit and they failed to allocate to my account. So now they are chasing me for something which they should have allocated. They have not provide me with a resolution to date.
