Citrus Payment Solutions — Zara online purchase scam

I made a payment on Zara app through upi and my payment got deducted but no purchase was made what to do .
I need a refund plus I got a call from consumer complaints and they also deducted rs 4000 I don’t understand how can someone be so unprofessional .
Specially big brands like Zara doing such things .
I need my refund do reply me to the earliest ( also for some reason after the call where they took 4000 rs I have blocked my card so kindly look into the matter ) and contact me back for a refund
