Rain Internet Sevice Provider

This is not my first time complaining about the very poor after service of Rain Internet services. I am in the process of relocating to another house and I requested Rain to change my External Rooter to an Internal rooter. By doing this, I will be able to take the Internal rooter to my new house without having interrupted internet services. This can also ensure that the external rooter will not be ****** after vacating my present house. I have made various calls to the Rain call-centre and was told that they will get back to me. They do NOT come back to me!!!!! My last call to them on the 5th of February, I was told that my request was escalated and that I will receive a call from them in the next 48 hours. NO CALL BACK WAS RECEIVED!!!! With the last call, I also requested to talk to the call-centre supervisor directly. The supervisor said his name was Curt, but he refuses to give me his surname, I doubt that there is any supervisor with the name of Curt!!!!! Here are all the reference numbers from my first call since the 16th of January: ***8, ***8, ***4 and ***8. The call centre agents are not informed as how to handle follow-up calls and the reply from them are all the same (feedback within 48 hours). Why doesn't Rain get back to their clients?? Seemingly they cannot handle the technical side of their client's complaints!!! PLEASE HELP!!!
