Breach of sale

I purchased 8 Monitors on 18th monitors from Firstshop and was invoiced and paid for the units via Credit card which was deducted from my account. When I came back to the office late yesterday afternoon I received a mail telling me that there was only one unit left and that was damaged, so they cannot deliver the monitors as they will not get any new stock.<br> The attitude from first shop was terrible and they offered me no alternative. I have bought several times from them and am now very sorry I did so. I shudder to think what kind of service I will get if any of the items will need to be repaired.
