ADT no feedback no refund

At the end of May 2015, we did a hand over to our tenant for a ADT alarm system, it was a new alarm system, we opened the account and in less than a month we had tenants moving into the property, we paid prorata amounts, ADT deducted again the amount for the monthly fee, and the prorata amount. <br> <br> I spoke to several people at ADT, Mr W Eloff from the JHB branch, he is a supervisor, said he will follow up and get back to me about the refund, I have been waiting since the beginning of July, and nobody is getting back to me , everytime I phone, I have to tell the whole story again, and again, they say they will get back to me! This is rediculous!!!
