Sold me an engine that is not working, and not getting feedback.

Absolutely frustrating! Bought a G4HG complete engine on Tuesday, on advisory I had to change the intake manifold and tapit cover. Once we took off the Tapit cover from the bought motor, the rockers where broken! I contacted Boston Japtech and they agreed to replace the head with a gasket and R1000, as per communications with Fernando. He dropped the head off after hours (which I appreciate) but no gasket, promises to send a driver in the morning with the gasket. By noon I have not received a gasket. It's Friday now and still gotten a gasket (last part needed) and all communications with Fernando only seems to be delay tactics, by right they were supposed to supply a new engine, but I did agree to the cylinder head swap as a compromise. I am still to receive the R1000 refund to pay for the engineering, I am an entertainer, and thus the weekend the car won't be running thus leading up to loss of income. I have send a message this morning and not getting feedback.
