PCS Basement Waterproofing Specialists

I initially contacted PCS waterproofing to fix a V crack in my basement wall around August 2017. After some negotiations Chris offered to repair the crack by injection with a LIFE_TIME WARRANTY for 725$ tax. On September 12, 2017 he came over and do the injection. He refused to clean up the dust or scrape the excess foam yet I paid him the full amount. After I spot a leak on Feb 2018 I tried calling him on his cell phone a few times without luck. I sent him two emails on March 19 and 22 and he responded on March 23 saying that he was busy and would get back to me within a week. Since I did not hear back I sent him 2 more emails on April 9 and 11 asking him to arrange a time to come and fix the crack. He again mentioned that he was busy and could set a tentative date for around mid May. I asked for a tentative date. Again I did not hear back from him. On April 29 I reminded him his legal obligation. Finally in his latest email on May 1 he refused to do the job.
