WC Wright & Son Overbilling and Shady Practices Birmingham Alabama

I requested WC Wright & Son look into a drainage issue I had at a rental property. They sent a service person out and replaced the drain pipes on 8/19/14 for the HVAC unit. However, I never received a detailed invoice for this work. On 8/21/14, the tenant complained about the HVAC unit not operating properly. I called WC Wright again and requested they follow up on the work performed, as the unit had been working properly before they began work. They sent another technician out who looked at the unit and stated nothing was wrong with the unit. The tenant called me back to explain the unit still wasn't working, so I called WC Wright again. They sent the same technician and this time the technician sprayed some FlexSeal in the drain pan and claimed this was the issue for the non-functioning unit. The tenants were forced to bail water out of the drain pan, which was not draining and I received an invoice for $213. The invoice I received explained the technician had spent 1.75 hours on premise to spray FlexSeal in a pan. The coverage spot was approximately 14" in diameter. I called and complained explaining I had been charged $48 for a can of FlexSeal, which I didn't receive, and the technician had spent 1.75 hours spraying a 14" diameter spot in the pan. The manager explained he didn't know what services were performed beyond what was written. I was also told for $650 more they could fix the pan permanently. In total, I was charged $213 for a can of FlexSeal and for the person to spray it at a spot (One can of FlexSeal at market price is $12). Additionally, my pan was not damaged prior to WC Wright & Son visiting.
