Spice Jet Airlines — Refund not received

My flight with spicejet on 10th april 2020 and 25th april 2020 was cancelled because of covid 19 lockdown... I first requested for the refund on 10th of june, they said it will be processed within 7-10 days, so i followed up and they again told me 7-10 and this way their tat for the refund kept changing and now it's more than 2 months since i filed the initial request and i am yet to receive my refund
