Jumia Have Scammed Me!!!!

Please what should I do,I transferred 67,975 to jumia last two weeks for item I bought,they said the money didn't go through,I was debited.I had to transfer the same amount to them at that same pickup station, before collecting my items, because they said it will be reversed.Up till now they haven't reversed it,and I called my bank they said the money was successful.Please my people what should I do.Even the items I bought,was not what I ordered for,they just used pictures to decieve people
