DROUGHT IN RAINS BILLING METHOD

I'm really appealed by the billing method rain uses. Their chatbot is also not the best thing under the sun.

The helpline number: *** doesn't prompt me to speak to a consultant or anyone from the company that's supposed to be providing me with a service. On top of all of this, I've been experiencing network issues throughout the entire festive season. I cannot struggle to get a hold of a consultant or a refund, it's highly unacceptable
