Uber India — Charged twice for same trip of 2018

Website:

Uber.com

In 2018, i travelled by Uber cab to the airport. Since my digital payment showed an error so i paid the cab driver in cash. Uber app still showed payment as pending and highlighted the concern to them. But they still did not confirm. Today after 2years when i booked the cab again they charged me again for that earlier trip. When i raised the concern they replied stating the case is 30days old and they cannot help. How could they charge for a trip that is 30days old.
