Rain and it's pathetic services.

Good day. Rain has been a nightmare. From the months of April, May and June 2022 I have had terrible service from Rain Internet Provider. There was constant Internet issues, I logged so many tickets to get assistance but nothing was received until I decided to cancel. Upon cancelation one of Rains agents called me and offered to send out a technician to assist. The technician came and the problem was solved. I used the service without a problem in the month of July and then suddenly at the end of July my service was abruptly terminated (No formal notification was sent to me regarding this). I then called Rain to find out whats going on and I was told they would call me back in 24-48 hours. THEY NEVER CALLED. I had to call them back again and telephonically I requested the service to be canceled as I already moved to a better internet service provider. A month plus later Rain has the audacity to reactivate the service without my consent and send me a bill for the months I have not been using the service. I took the Sim card out of the router in August when the service was inactive. Rain is committing ***** by billing me for something I have not been using. They are the most unprofessional when it comes to customer care and general customer assistance. How does ICASA even allow such bad services to be rendered when it's not lawful (Who pays for something they not using or yet how the hell can they reactivate a service without my consent?) I want an immediate cancelation and no bill sent to me because I have not been using rains internet since the end of July when they terminated my service abruptly.
