No reply to my emails - just not bothered!

I would like to have my debit order changed from one bank to another. I emailed MiX Telematics accounts on the 3rd of September, I did not even get an acknowledgement email. On the 6th of September, I forwarded that email to customer care. This time I got a reply with a reference number (***4). That was a week ago.

When do you plan on assisting me with my debit order change? After the month is over? After this year is over?

I should stop the debit and see how fast you email me then!

I am way past my contract period, maybe I should just stop your services and go to a competitor, even bad service from any other tracking company will be better that being no service at all!!!
