Bad service delivery

My partner and I recently bought a vehicle and we decided to go with No Jack. We contacted them and they sent the rates and packages. We chose our package and went to install it at the office. We were told they cannot do a call out with the special. Which was fine because I thought we would be saving on instalments. After we signed and did the installation, there was so many hidden fees that it took the bill to almost double. Firstly the amount that we were to pay monthly increased. When installing the tracker we were told we have to pay for the full amount for the month as we installed it on the 14th and not the 16th. We were not provided with an adjusted rate and now must pay for days we did not have it installed. Please be wary of their hidden fees. It’s crazy! And worse part is, you sign a 36 month contract that you can’t back out of after the installation.
