Rain Internet Provider not sticking to agreed dates

Dealing with Rain Internet provider in South Africa has become an annoying experience. My scheduled date of account payment for my home wifi is the 1st of every month...even on the Rain Mobile app I set the 1st as the date. However these idiots keep cutting my wifi off on the 25th of each month. Last time I struggled to get them to cut off my second wifi router from the network...and they kept charging me.

What kind of nonsense is this? Does Rain have competent and professional people at all.

Come on Rain do your job. Fire the imbeciles that are sleeping on the jib.

Please correct my account payment date immediately.
