Bad attitude

I logged a complaint on the 28th of feb, nobody contacted me to hear my complaint but to my surprise I received a response saying that\ we are pleased to inform you that your complaint is resolved.I really fail to understand how can someone just say that without even contacting me. I received a call from another agent saying the same thing as the one who called me previously, very bad attitude. Rcs needs to train their agents on customer service and respect to customers. They all need to change their attitude and treat customers with respect"
