Best Crack Injection in Charlotte NC

I contacted American Leak Detection online and requested service because of a frozen pipe in my front yard. The women who called me was fantastic. Very friendly and professional. A team of 2 people came out to locate my leak. They charged $700 up front in order to locate it. They marked the spot approx. 3'x3' I spent the next couple days digging, and went down over 3 feet. No leak, not even a pipe. I called the company back on a Saturday, and there was no answer. This is understandable as they were closed. I was unable to leave a message because the mailbox was full. I ended up digging from my water meter and found the water line wasn't even close to the spot they marked. I called back during business hours and spoke to the same women. She requested I email photos showing where the leak ended up being located. I sent these photos in via email. I requested a partial refund (not 100% as they did have time and labor here) I received a call back 6 days later from the owner Dennis Fair. I believe this guy is the owner of the franchise in this area. He was very rude and honestly just a complete D-bag. He asked why I didn't call back, and when I explained I did, and the voicemail was full so I couldn't leave a message he said that wasn't true
