Myntra.com — Refund initiated but not received to my account

Website: Myntra

As per Myntra, refund amount had been initiated on 18th, 19th and 20th March but I haven't received the amount yet.
They have provided me with the bank reference number but SBI is saying that reference number will not work and they need UTR number which Myntra is not providing. Refund is for around 23 products which amounts to around 25000 rupees.
Below are the few reference numbers which they have provided.
