Ola Dash Complaints & Reviews

Ordered few items from OLA Dash today.
One of which was Madhur fine grain Sugar.
But they delivered another Sugar packet, i just wanted a replacement. I even told the same to delivery person at the time of delivery but as he was not aware pf anything I thought it’ll be sorted after discussion with customer service.
After raising same with customer service they said they are taking this on priority but after 4-5 hours...

I have ordered some groceries (milk, curd, cheese etc ) on 02.04.22 at 10AM.
There were 8 items, that I have placed an order, & out of 8, one product was wrong, 1 was expired & 2 was nearing expiry. So I have returned the full order to delivery agent (Subham- [protected]).

But I didn't receive any further communication from ola store/ refund the amount & after contacting ola, they are asking for evidence.

If...

Ola dash provides 10 min delivery and only pre paid orders, i have ordered a few times but most of the times some items are not delivered. Delivery guy says contact ola support for refund but there is no response from them .
Presently around 500 rs worth items are not delivered and money is not refunded.
Please provide solutions....
