DSP Plumbing review: The plumber came only 17 days later after our calls and failed to detect leak

My husband called to DSP Plumbing and informed the receptionist that we needed a plumber, because it was leak in our property. The receptionist took my husband’s name and address. We waited 10 days and the plumber didn’t show up. My husband called them again, and the plumber came 7 days later. He made some holes, checked something and he said that he could do nothing. He couldn’t detect the leak. We needed to hire another company.
