Subscription termination

I am a customer at rain, however my account is somehow overdue which I tried to make contact with them and payment arrangement because I will only get my money on the 15th. So I have to pay 626 for my monthly subscription so I asked them to pay half the amount in order for me to use the wife then the remaining balance I settle it month end but they refused which subsequently led to them terminating my services or rather disconnecting my wifi services citing that I must settle the whole amount which for now I don't have as the funds I'm waiting for will only be paid on the 15th
