This company purchased my commercial building and supplied me with an invalid HST number. Revenue verified this number and it was not an operating HST number After numerous attempts to clear this up they washed their hands of it. Now Revenue Canada is after me for over 140,000.00 plus interest on HST that they should have claimed This has been going on since Oct 2017. Both Lawyer have tried to make contact with this company with no result. I would recommend anyone dealing with this company to check the HST number they have supplied to you so you do not end up my situation as this is costing costing me thousands of dollars to try to clear up something that is not my fault
