Wish complaint: Internet fraud

I have bought an item through Wish app 03292020.
I paid for that item $235.42 the same day, including for the item itself $217.00 minus promotion $21.70, Shipping $20.00, and tax $20.12
The tracking of the item showed that it never was sent to me. After multiple requests I received 05292020 partial refund fort delayed delivery in amount of $13.06. After repeated attempts to get full refund I was instructed by Wish customer service to apply for it after 07142020. After applying for full round, I have repeatedly received answer that full refund already was sent to my account 03292020. Wish placed a statement on the item page that there was partial refund sent 05292020 in the amount $190. That statement is not true. I answered to customer support that it was a partial refund paid at 05292020 at the amount of less than 6% of full payment ($13.06 out of $235). The answer I received 07172020 stated that refund window for that item closed 07192020 (that date even didn’t come yet).
