Unbelievable service ever

I'm not happy at all and I'm so whiling to take this further. The device was install already in January it was the agreement between the dealership and you guys and after installation I was told I will get a call till today but I get SMS that I'm owing I must pay or I will be listed how so I cant access the app nor track my trips I called yesterday for cancellation I cant cancel y? and I called with no help the I went to install the device of my choice now ,poor service ever wouldn't recommend to anyone the agents are very rude when u call to call. the sad part no debit order ever went through but I'm gonna be listed.
