Is there any precedent to have a purchase made with crystals refunded?

My 2 yo son was playing with my phone and bought grief karga 32 shards for 1280 crystals. (Already at 7*) messaged EA and they said they did not have the option to do anything about it. Just bought the £19.99 pack on May 4th. And have spent £35 in the pass few weeks. Seems they’re happy to take your money but not help out after. This is the first time I’ve had an issue and contacted them.
