Business ProfileforGreat Northern Insulation

In Mar 2023, I contacted Great Northern Insulation (GNI) for a quote. At this time, sales rep ****************************** inspected my home by drilling 2 pilot holes in my living room. He confirmed that we were a candidate for drill-and-fill wall insulation. I was quoted $10,079.60 for the job. The quote went stale as we prioritized other renovations. In May 2024, I called GNI to refresh the quote. Sales rep *********************** came to inspect the premises and re-issued the quote on May 10 for $10,079.60.On May 22, I paid a 40% deposit ($4,031.84) via e-transfer as per GNI's instructions. On June 9, ****************** from GNI called to ask if he could view the property prior to the insulation job, which I arranged for him to do same day. *** had now inspected my property on 3 different occasions.On June 11, ***'s crew arrived as I was leaving for work. I received a call from the crew lead later that morning saying they had abandoned the job due to existing insulation found at 2 pilot hole sites at opposing ends of the house. They shared photo evidence, patched the pilot holes, and left before noon. I was told by the crew's lead person that my sales **** ******* would be in touch with me regarding my deposit. I did not hear from ****** that afternoon. When I texted ****** on June 12 to ask if I could expect a refund of my 40% deposit, he confirmed that GNI's office would be in touch. After 2 weeks passed, I called the office on June 25. They confirmed that a refund cheque had been issued. On June 28, I received a $3,184.34 refund cheque in the mail. This is $847.50 short of my deposit. I emailed GNI's customer service and *********************** that day to report the discrepancy and request that they contact me to rectify the error. Nearly a week later, I still have not received a response. Based on the quote's language, I believe the deduction applied (if intentional) is arbitrary and unlawful. No sales receipt nor explanation for a charge was ever provided, either verbally or in writing.
