Poor service, unauthorized debit.

On the 19 of July 2020 I received an sms stating my battery was disconnected which was never the case. I then called their csd dept and the lady advised me she is testing the signal. She did, and the point was incorrect. She advised she will reset the system, till date, my vehicle shows its at my residential address. But last night I was debited for R400. A consultant had called me to say auto and general advised them to install a device in my vehicle, which is bull****. Why would I install another device.
