Billing issues and data

My problem started last month with billing and not getting a service. I was billed while my data was not loaded. I'm on limited wifi. I called rain made arrangements paid last month and finish off this month. I called 2x during the day was told my data will be allocated on the loop. Now 3rd time I'm told only on the 1st.im not getting an answer why am I paying the 25th but only getting usage the 1st. They are still owing me for the January I paid but didn't get data. I last month sent quiry to support but nothing was resolved. One agent tells you this and the other another story. Their agents am have different information.
