Haras*****t from their agent continues

At 09h50 on 25/1/2018 I again received a telephone call from GDS Security, an agent of ADT Security, asking me if I wanted an alarm system.

Even if I wasn't an ADT customer already I would NEVER buy anything from people who continue to harass me like this.

I have told them 3 times to stop, but the harassment continues.

It is probably time I registered a complaint with the National Consumer Commission, as it has proved impossible to contact any senior management in ADT. Their staff just don't care, and keep you holding on the call forever.
