Excessive Response

During the month of October 2014 we received excessive calls from Chubb indicating that our alarm has gone off. I, unbeknown about increases in response calls, instructed the response centre to go and check on my practise. We phoned for a technician and was informed it will cost R700.00. This happened a month after my warranty had expired. My bank account was debited with R752.40 end off November 2014 for EXCESSIVE RESPONSE without notification. I wrote a letter of complain and received no respond. I was not informed of the monthly payment increase.
