Ajio — Not getting my money since from 1 year

I got the refund of a product last year which I purchased from Ajio online but the mobile number on the account is not with me physically as my number has changed now...I am constantly Calling on Ajio customer service and sent lots of emails to change my old number with new one as it's required to withdraw money from my account as otp goes to the registered number everytime.The otp is also not going to the registered email of which I've access ...
The Ajio customer service has badly treated me by not changing my new number after several requests..They have caused me huge harassment and made me feel like I'm a dumb.Everytime I called up here, n everytime I had to tell my story to every representative repeatedly and they wasted my lots of time.They were never able to assist me and always gave me false hopes.I m very badly affected from 'Ajio Customer Service ' behaviour...I am completely pissed off as it's been one year and still the issue is not yet resolved.Very very poor Ajio customer service👎🏻
