Business ProfileforServpro of East Dallas

I paid Servpro of East Dallas $731.06 on invoice ***** for services rendered at my home 7/24/23. They agreed to clean and deodorize my condominium prior to the closing of my condo, a requirement of the buyer in our sales contract. When my realtor went by on 7/24/23 to inspect their work, he found it unsatisfactory, saying it looked as though it had not been cleaned at all. I immediately called Servpro of East Dallas, who agreed to send their team back to re-do the work. After Servpro of East Dallas said they completed the work a 2nd time, the buyer's realtor went by my condo to inspect their work, and found it unsatisfactory a second time. There were bugs on window *****, debris on the floor, grime on the microwave, debris on the countertops, and when a rag was run along the floor, it came up dirty indicating the floor was not cleaned. The buyer's realtor said it needed to be cleaned a 3rd time, and my realtor agreed. I called Servpro of East Dallas immediately to inform them that we were hiring a different company to clean, as Servpro had proven twice that they could not complete the job. I paid another company to clean my condo. I spoke to ***** from Servpro at the time, who asked me to email photos to ********************************************************** and ***** agreed to process a refund. The photos were emailed that day (7/26/23), however the refund still has not been processed. I have reached out to the company by phone and by email multiple times, and am not hearing back from *****, ******, the receptionist, or anyone else on the team. I have emailed 7/26, 8/17, 8/19, and 8/28. I have called and either left a voicemail or been told ***** will call me back on 7/28, 7/31, 8/10, 8/15, 8/17, 8/18, 8/19, and 8/28. Over a month has passed since the promised refund, and no refund has been processed. I find this unacceptable and need help.
