Bad service provider

I have been getting lot of calls that I owe a certain amount and when I ask for explanation, no one is giving me a proper explanation where it is coming from and when I ask for my statement I am not able to be assisted with. When I check my debit orders on my bank statements, I am able to see double debit orders on my statement and when I ask where is the money allocated to none of the call centre agents have an explanation for that.

Secondly my installation did not pass the inspection and no one has came back to resolve the failed items until this day but debit orders are too quick to leave my account, this feels like a financial harassment now since no one is able to address this matter to me to understand why was I debited the amount we did not agree with and I have raised the inspection failure report multiple times but I am still not able to get assistance. Totally a waste of breath and my time to answer the calls lately. I am just waiting for my contract to expire and I am cancelling their service as It's been long overdue and I was also patient enough up to this point. Imagine paying for a security service that hardly works and the patrol cars are not even visible in our area, so if I was you I would do my research properly.
