Swiggy — Misguided in buying their swiggy dineout pass

Swiggy dineout pass which i Bought for 500/ month, this is full useless, when i was buying they showed many restaurants in it but i bought it and then i could understand half of the hotels are not there and also the news came in that most of the hotels have delitsed themselves from swiggy dineout, leaving very few options of veg restaurant for me, i tried to contact the customer care but they refused to give me a refund, after some time they just stop replying to me also, till date i have still not used that pass thinking that I'll get my refund back beacuse they misguided me saying there are so many restaurants but in reality there are none, currently only 5-7 veg restaurant are listed on that app that too some of them are very very expensive hence i cannot go to anyone and my money got wasted
