RAIN SERVICE PROVIDER NEEDS TO BE SERVICED 1ST THEN TRY TO PROVIDE A SERVICE TO CLIENTS

I have had endless issues with this service provider, eventually after a month i got my refund for a non working device and rain collected the device. I have now opened a new account and had recieved my new device on the 20 April, i have paid the amount requested. i now have an sms to say the device service is cancelled outstanding a payment and we still running on the cancelled device contract - what is wrong with this provider and the measures used to keep everything on track, can someone fix y account this is a nightmare dealing with rain, and not a single rep ever calls me back !!!! THIS IS EXHAUSTING
