I had Greg install a radon mitigation system about 2 years ago. After several phone calls to come and test the first unit they finally did. The test results were too high. They enlarged the hole under the cement. Re-tested. Results still too high. They installed a larger unit. This is where I can not get Greg to return my call to come and re-test the new larger unit. After 3 weeks of phone calls, text messages Greg has not returned my call as of 2/16/11. Very poor customer service.
