Incorrently billing

I made a payment on my account dated 2022-11-29, then I changed the payment date to the 1st of each month due to my resignation. on the 15nth of December my account got disconnected due to non payment . I called Rain dated 2022-12-16 @9h46 and 16h47 I was told that they received my payment, the matter will be escalated and made a promise to pay for month end December for connection purposes. 2022-12-17 @ 11h00 I called again and i was told they are maintaining our tower and I should relax while my account was showing non payment message and I will get credited for non connection on the rain account. Today I called Rain and I was rudely told that I need to pay My account, Meaning the billing cycle was was only for 15 days not the 30 days. I am currently buying Data using my own money. Rain is refusing to re-connect my services insisting I should pay. they cannot transfer my call to a manager because he will not entertain my request because I need to pay my account again . Ref number for the call ***
