Best Tub Surround in Phoenix AZ

Clyde came to our company to gain our business. We manage 400 single-family homes throughout the valley. We gave him two work orders. One is over a month old and we still don't have an invoice although they claim the job is complete. The roof is still leaking and they say it is not on them because there are holes in the metal stacks. (So as a roofer I guess they won't do all of the roofing repairs - metal stacks in a roof are someone else's job???) Could have told us that a month ago so we could have avoided further secondary damage to this home for the owner and major inconvenience to our tenant.
Second job we gave them is still leaking with each rain. 16 days and counting waiting for a bid. We are reassigning the work order and will not use this company again.
