Rain is really a horrific WiFi to have

I made payment on the 29th February and again on the 17th and when I made the one for the 27th I spoke to that chat agent and they told me my acc payment date was changed on there side for the 25 and told them I don't get paid on the 25 and that's how I paid on the 29th of Feb then they demanded another payment on the 15 yet again I told them y is my WiFi off again she said it's changed to the 15 again I had to make payment on the 17th of March. I asked for payment date to change for the 1st of each month and confirmed that my next payment will only be on the 1st of april.now you expect me to pay again No you guys are taking me for a ride

It's 5.51 and still no one called or is trying to sort out my problem now that's what we call bad service and I'm still offline

I paid on the 29th January then you guys switched off my WiFi on the 16th of Feb I paid again on the 17th as per the call agent my next payment was to be on the 1st of April,so what you telling me is my payment on the 29th of January was only valid for 15 days of WiFi and the I paid again in the 17th of February was only valid for 12 days of WiFi so now I pay again and only have access for what 10 more days.my first agreement when I got the WiFi I said I get paid last day of the month it worked fine till they changed my date for the 25th ,then to the 15 now again to the 1st .it's really not fair I'm having this problem.when I paid on the 17th the call centre lady told me my next payment will be on the 1st of April now you want more money yet I just paid.so I must pay Avery 15 days that's not a full month cycle.

Does it make sense to pay on the 17th and again on the 1st so how many days service do I get
