Yes i know that. till 50K i get 1RP per 100 thats 500 Rp for 50K transaction after that 10x for 2K transaction is 200Rp total should be 700Rp for 52K transaction. Whereas, I received 1200 Rp.
I guess they have marked the 50K transaction as POS transaction and they credited 2x RP for that transaction.
