Rain Internet is a no no

After cancelling my service in 2023, Rain has left me alone for about 6 months and all of a sudden started to harress me with phone calls regarding outstanding payments even though I haven't used the service since 2023 when I cancelled. On the 15th of August they just deducted a payment. Their whatsapp message service is permanent answers by a machine promising call backs for days now without anyone calling me. A waste of time and money with disgusting customer service.
