Ola Cabs / Ani Technologies — For someone mistake I being touched by Ola customer care

I used Ola ride about 6months back. After my ride have settled trip amount to can driver . Later 2 days received an SMS mentioning to pay Ola money, this was very surprise me as havent intiated anything . Also I don't know when got Ola money get into my account. On 3rd day issue was escalated to customer executive, but response was unethical/unfair simply mentioning that it should have been highlighted on same day even after my above explaination. So have discontinued service now I am being threated to pay outstanding dues.
I am ready face challege and have already raised consumer complaint . So friends message is don't use OLA SERVICE it is literally hightech fraud.
