Cut off for incorrect billing from Rain's side

First of all, I feel this is very unprofessional of Rain to keep me in arrears while they were at fault not deducting my account for 2 months in a row, now all of a sudden it does get deducted. and why deduct on the 26th when I said I get paid end of month, You cannot harvest apples from a tree that you just planted

Okay so last month my account was in arrears, I paid it on the dashboard with my banking details, the next morning the money was paid back to my account by Rain, The same afternoon the same amount was deducted from Rain as it is supposed to be. Everything good, my internet is back, last week it was cut off again, logged onto my dashboard, telling me I'm in arrears, so I clicked on the pay by 26th of this month. (Which I clearly stated that I get paid end of month and it should be deducted then, but no not them...)my internet WAS working again.

NOW TODAY MY INTERNET IS OFF AGAIN TELLING ME I'M IN ARREARS AGAIN?????????????????????? 2020/05/2018
