Debit Account - Cannot tell me why - Still not!

OK so I posted a complaint a few days ago and Discovery phoned me, told me they will get back to me within 24hr. OK so they did, without an answer as to why my account was debited. Again I was told 24hr. Today is the 30th of January, just a bit more than 24hr, about 2 weeks and a few days more! On the 19th they installed this DQ Tracking thing on my car to track my driving. Guess what...The web site tells me there is a problem with the Device! This since installation when the gent told me all is working.<br> SO no I have a debit on my account without authorization AND a device that should \HELP"save me money that"
