Disgusting disregard for a R40k unauthorized debit

I am contracted with Blue security at my establishment on Davenport in Durban. In December I approved a quote of R16k where work was done and I was billed. At the beginning of May when they took their monthly premium, they went onto bill me R42k. I enquired on Tuesday last week via multiple emails as a call Id made earlier in the day did not yield me any feedback. I was not fedback until I had to call again on Wednesday and still no info provided to me as to why I was billed so much of money without any of my knowledge. I further emailed only to get a call assuring me that a customer consultant would be calling me. She did but no info as I required, I was simply told it was for work done in December, when i advised that for that I had approved and paid R16k, she no longer had feedback. I am extremely disgusted and disappointed in their carelessness towards such an unauthorized debit.

Further to that, even though in December new sensors were put in, I had a break in in January were the alarm system did not go off. Their incident report was only sent go me at the end of Feb.

Blue Security has shown me that I am not taken seriously as a paying customer, their disregard and lack of urgency towards me as a paying customer (both commercial acc for business premises and personal acc for home).
