Securezza putting company at risk and not taking responsibility for theft

Our company had been with Orion Security before and then in October 2019 our contract was taken over by Securezza. We did not know that Securezza was the new security company who took over our existing contract at first. When we had issues, I learnt that I need to contact Securezza’ s owner - Eric. Eric came to see me, and we agreed that we will carry on with the contract we had with Orion on the same terms as we had with Orion which was a month to contract on that stage. We then agreed to this. In December our company had our annual shutdown and during this time on more than one occasion, the security guard was not at the gate to open for people who had to come into the offices. On one specific occasion the guard was caught watching TV and not being at the gate. When we opened in middle January 2020, Eric was informed about this and we also gave them notice that we will not continue with the current contract we had. He was told that we would stop the contract effectively 1 February 2020. He asked if there was anything that he could do to change our mind, but we have decided that we don't want to continue with Securezza. Our payment terms with Orion was that we always paid upfront for guarding services which we had done every month. Our understanding thus was that Securezza was paid for until 31 January 2020. On Friday 17 January I received a phone call from Eric asking if we are still going to pay them at the end of January to which I replied that we will not be making payment as in our mind we have already paid for January. Eric told me then that he will have to pull away his guards, but that he will speak to his operations department and come back to me. I never received a phone call. When one of our employees came to the offices on Saturday, all the remotes that were used by the security guard had been left in the unlocked guard house and the warehouse doors were left open. The security guard was taken away without our knowledge. I phoned Eric again on Saturday to which his reply was that he will find out from his operations department and come back to me. Still no reply from him. Our company was thus put at risk with Securezza actions. We then realised on 22 January that some items were stolen from our premises on Friday night. After investigating and looking at security footage, we saw that it was the security guard who took the items. Eric was informed about this and his reply was that he can't work for free and that the best he can do is to help me open a case at the police station. It is our company's fault that Securezza was not paid the money by Orion which we paid for the contract when Securezza took over from Orion. It is very unprofessional for any company to just pull your security guards, without informing the company and then not to take any responsibility for theft by your own security guards. Please think twice and be careful when dealing with this company as clearly, they don't have their client's best interest at heart.
