Tuff Shed

Ordered it on Sept 3, 2020, no communication until early Dec for installation, I called numerous times for any information regarding dates and pad requirements, they never called back! Rescheduled installation twice due to COVID, that's fine. One occasion no showed up, no call, next no show, but they called! When they did show up there were no shingles, trim boards and the ramps they sold me were "never" offered but they were on the sales order they signed off on, so they sent three foot ramps after selling me 6 foot ramps. Two weeks later they still have not completed the shed, upside is we have had a chance to look at it and find no studs on the door wall, the side wall has wall studs however there are no nails on two of the studs, the shingles are blowing off, still have no trim or drip trims and they are harassing me to sign off on the job as complete. I do not blame the contractor, he was given a poor quality product to work with and had to go to the hardware store to purchase shingles just to install them as well as a few other items to cover the insufficient factory issues. Tuff Shed will not return my calls or provide me with a schedule for completion.
