Business ProfileforA 1 Waterproofing

I hired A1 Waterproofing in Feb /22 after discovering water in the back porch of my recently purchased home. The owner/operator, ****, was initially responsive, but I quickly began to see signs of unreliability (eg. not showing up at agreed-upon times, with no advance notification). Nevertheless, the job proceeded and was completed in April /22. My complaint pertains to the subsequent commitment made by **** in early /23 after I discovered that the waterproofing his company completed hadn't fixed my water issue as guaranteed. When I called **** about this on 9 Feb /23 he said he stands behind his work and would resolve the problem. In the weeks that followed, he didn't show up at several agreed-upon times and stopped answering my communications. I called his cell and company numbers repeatedly and left many voicemails. On 5 occasions, I couldn’t leave a voicemail because his mailbox was full. I left messages with his admin staff on at least 5 other occasions. After a month of unsuccessful calls, I sent a text message on 27 March /23. It went unanswered. I kept calling for another 2 weeks before receiving a text from him on 14 April /23 (his first communication with me since 21 Feb /23). He apologized and committed to handling my concern promptly. We agreed that he'd complete the work on 21 April /23. He didn’t show up. I kept calling for another 3 months. My calls weren’t answered and my voicemails weren’t returned. I sent **** another text on 20 July /23 but again didn’t get an answer. My last effort to reach him was on 31 July /23. My call was answered by his admin assistant, who reached him on another line. She said he couldn’t talk because he was on a job but that he promised to call me back in 1 hour. I didn’t receive a call. Screenshots of text messages I exchanged with **** between 28 Feb /23 and 20 July /23 to are attached. I have lost faith in A1 Waterproofing and am requesting a partial refund for the ineffective waterproofing work around my back porch.
