Account debited ********ly

In Jan 2015 we called Chubb out to look at and evaluate our alarm system. Needless to say all we got was bad service and no help. We were charged R582.00 for the non-service, which I complained about and it was assured to me by Sonika Terblanche that this invoice was to be credited. On 21 Nov my bank account was debited by R582.00 which I was told by their accounts department was for the supposed credited invoice. Yesterday I forwarded an email with all my proof to Leigh Mc Coy, Sonika Terblanche and Bulelwa Nhlapho. I advised in that email that if I had received no feed back by COB yesterday then I would start posting on Hello Peter and social networks. So seen as though I am writing this you can imagine that I have had no feedback after a reminder email to all 3 of them this morning at 7.08am. I will be posting this complaint every hour on the hour and the next one will be on Facebook as well.
