I'm disappointed in you rain your service is not what you are advertising

People please make me understand. Since January been asking rain to move my payment date to the 7th of the month and I was told they don't have 7th on their calender staring from 1st so I chose the 15th of every month but I'm telling you every 1st of each month they disconnect my services after a lot of tries to debit my account. On the 24th February I called rain wanting to double check that my payment date is indeed the 15th and I won't be debited on the 1st I was told yes everything is sorted. Only to be woken up by my banks notification that rain tried to debit. People I've been saying this over and over again that I can only have money on my account starting from the 5th of every month not the 1st. This is affecting me badly at bureau. Now this morning again same this after I called them yesterday and now they have disconnected my service I have no data whatsoever. Oh I'm so disappointed in you rain I chose you because I thought your services is much better now I can't even recommend you
