This was a $79 for 15-vent deal that I purchased from Wag Jag. Extra vents would be charged $9/ea. I tried to make an appointment for weeks, but only got their answering machine. When they (finally) returned my call, the representative up-sold me to the "VIP" service which included a rotary brush service, sanitizing, etc. for an extra $75. I told the rep that I couldn't afford the $75 for the VIP package plus the extra $9 per vent -- she informed me that if I purchased the VIP deal, the extra vents would be included.
The evening prior to our scheduled appointment, I received a confirmation call. At that time, they tried to tell me that it would cost what I paid for the Wag Jag voucher, plus $75 for the VIP package AND $9/each per vent. I told them that wasn't my understanding and if they were going to charge me per vent, I wouldn't be purchasing the VIP package. Our appointment was confirmed for the following morning at 0800.
The morning of our appointment (for which I took the day off work) no-one showed up or bothered to call. I tried to call them and (again) got their answering machine which identifies the company as "Ontario Air Quality".
Upon doing a little research, the phone number listed on the Wag Jag voucher and their company website (www.monsterduct.ca) is 647-833-2293, a phone number which is associated to a variety of different duct cleaning companies with dreadful reviews on HS, Red Flag Deals and the BBB. This company puts itself forward as Doctor Duct Cleaning, Total Duct Cleaning, Monster Duct Cleaning and Ontario Air Quality. They are ALL the same company.
Fortunately, Wag Jag are professionals, even if Monster Duct is not. They have refunded my voucher in full.
