Worst service on complaints

Had the EPS System fitted 16/09/2020, it was advertised as giving me a saving of 40%. After installation I noticed that my power consumption is not changing and in some months it is even more than before. I logged a call and multiple emails on which I was ignored. After contacting the CT-International company that finances eps systems they could not assist me either and advised me to continue trying to contact eps systems to get the problem resolved, or remove the system and refund me. To date 4 months later, I have sent them all information that they have requested and still no resolution. The worst customer service I have ever experienced in my life, and now I am paying my normal power fees and the fees for this faulty worthless system.
