Tasco Appliances

Purchased a Wolf microwave and built in oven. Had a pre-site visit by Precision Installations using Wolf's concierge service. Had to remove the old oven myself. Done. Had to have an electrician come and change the box in the space myself. Done. Now they claim that there is some trim to be cut so again will not install the oven. Both are still on my kitchen floor and I doubt Precision will ever agree to install them. Paid an outside company to come and install them. Hopefully soon as oven has sat a week on the floor. Zero customer service from Tasco and no help at all. What sort of install company cannot fix minor issues?
