Rain ****s me by charging me 2 weeks before my preferred payment date and cancellation during January and shuts me off the network

Rain really doesn't keep track of its customers payment date I mean seriously, First last month I had to go through a long procedure of cancelling my SIM card and waiting for January the final due date to arise because somehow they're more greedy to get their hands on more money even after the day you paid for the present month but will still charge you for the final month as well Which I'm skeptical whether it will be functional since I won't be making payments for the next month after that since this concludes the cancellations. Anyway Apart from this....What really shocked me they change the payment date option to be as early as possible I mean 31th & 1th between these months for the people who cancelled from December I mean I usually pay on the 15th or 20th cause that's a preferred date some of us get paid to have uncapped internet connection for almost 30 day's till the next payment date but it's only been 2 weeks/14 day and yesterday night my network had no bars you know how many people I missed to shout out Happy New Year and wish them well on WhatsApp, Discord, Instagram etc. But you blew it cause I can't even change the stupid date option to pay for January the two SIM Cards I cancelled even had 15th January to be cancelled.

So why are you making unprofessional demands while my wallet is full of moths? Surly I'm not the only victim who's been ****med this way I've seen many people complain about the system and network daily but you don't take action for it? If you're own system says on the preferred date then wait for that date but **** it you literally want the money early as possible robbing people a worth while month of internet connection in 2 weeks including removing the option to satisfy your greedy purpose for more excuses
