Bad setvice

I have been calling rain billing department for my rain account in regard with my payment date,promise to pay, *****ulent activity and my id number being used for 3 different accounts which 2 of them being told that they are not active as it's only 3 months to date that I've been using this router. I called so many times since from last week and was told that my issue will be resolved as their system was too slow and giving them error message. Then I was promised that I will get a call within 24 hours which I did not and yet my matter have not been solved or escalated to the relevant department. Now no one is advising me regarding this issue
