Overcharge

I have been a loyal client of ADT for a number of years. I've maintained an excellent profile with ADT for all these years, and would assume that they wouldvalue me as a Client Sadly, with ADT once you are a Client, you have to take care of yourself. I was out of contract for months and being overcharged and only when I queried why I was overcharged, I was told it was my responsiblity to renew the contract! Seriously, ADT wants me to ensure that their business stays afloat. Nevertheless I signed a new contract, only to query with our ADT with neighbours in the area, and it turns out I am still paying too much. Sharon Naidoo then contacted me and advised that as at November 2015 I will be charged R225 but I am still being overcharged. When I queried it with her, she send me abrupt emails saying that the new rate will be effective from February 2016. so unprofessional
