Disappointed with service

I am devastated with the conduct of Rain wifi. I have not been able to connect since Monday 24 October 2022. I have been calling them every day and all they tell me the problem will be fixed within 24/48 hours and yet nothing has been done. I have also logged a call to the service department still nothing. I have been a loyal customer with them since 2020 and even upgraded to 5G. They are telling me if I cancel they will bill me even for the time I'm offline. Their service is terrible shame, I wouldn't advise anyone to use them. I have missed several classes online and my exam is starting next week and Rain is doing this to. On top of it I have to waste my airtime calling them and have to hold for more than 10 minutes before they answer you. Terrible service.
