Disgusting service

I am deeply aggrieved by the service i am received with Rain, they are busy harassing me with messages of making payment while i made payments for Jan and February month, and i have sent proof of payments for this but their billing department is not allocating the money correctly. I called the whole of last week with no assistance, spoke to their AI robot on whatsapp with no assistance. I spoke to different support consultants like John, Jonel and many more promising to resolve the issue by escalating to billing department but no one has ever called me. I spend lot of money calling without success and yet they send me messages to payment for the services that i already paid for.

No one has answer apparently, the support team, they can only escalate but do not know what is happening with billing department. I have been with Rain for 5 years, and i deeply regret joining them as they do not care about their customers and their not honest about their service.
