Payment issue

I would like to display how upset and angry I am with this service provider, if you are someone whose new to rain or who is considering using rain don't cause you will be going through alot with rain . I have never had any issues besides network issues with rain which I always had to complain to them about. But the main thing here is that in beginning with of march when I got my bill I reached out to rain to ask for a payment arrangement like I always do as I'm currently started a new job and I haven't gotten paid like I should have so I arranged with one of the agents who called me for a promise to pay and I told the agent on the phone what I could afford to pay that day and then I told him I don't have access to the SIM card of the number that's registered to rain and he told me no worries he will send me the payment link to my email I made the payment so when my new work advised we only getting paid the remaining of our money month end my partner advised he will pay the remaining balance on the 28th I was then told that I have to pay 50 deposit I advised I don't have the money and I made a way to get that money just to be told they can't send me the link of payment mind you I never had to pay a 50 when I contacted rain to make payment arrangements but suddenly now I have to and now that I have the money they making it so hard for me to make payment. I'm so tired of this service provider honestly I can't wait to cancel with rain I just wanna be done with this service provider pathetic customer service they don't even attempt or try to understand I told them the agent sent it to me via email and now they saying it's impossible like how ? When it was done I can't deal with stress I'm pregnant and then I have to deal with this stress of rain whose customer service agents don't wanna assist how is it impossible to send a email with the link it's my blady email
