Rain service

Hi i didn't request a cancellation on my service I want the wifi connectivity problem resolved and no one called or did anything to assist . I had a similar problem a while back and an agent called me and fixed it. So i know it can be fixed. What happened now is it works but it’s on and off ( this is for the last 2-3 weeks) Why am I paying for 5G service which is meant to be the best but works for a week then the rest of the month very slow im not happy with that. Then I receive an sms that my account has been suspended due to non payment.
