Saving telephone bill

So disappointed about this company m their client who is paying premium everymonth but to them its not enough. Adt can not take their phone and phone the client if there is a problem. They keep on spending me message like this (Fidelity ADT JHB: Dear valued client, please contact our call centre to test your alarm. Preferably Mon-Fri, 9am to 3pm. Acc no: MDL00157.) Since last year i havr been receiving this .m so suprised that to them its not a worry if the client is not responding to their message. They are the service provider and they are supposed to render a service to me not to save their resources at my expense. As they keep in sending endless message it's like thy are saving their telephone bills. So disappointed about this. I have notice that there is a problem witg my battery. They have never boarded to call and find out why m i not responding to their message. Phoning client it's a crime to ADT security company wht is important getting money .They need to improve this bad bad service.
