Mobikwik — overdue amt. paid back but lien on my counterpart party's a/c not cleared

Address:	Gurgaon, Haryana
Website:	www.mobikwik.com

Dear sir/madam,
I recd. Below message on my mobile no.[protected]:
“rs. 8589 is due for payment on account of an inaccurate bank transfer. Add rs. 8589 more to your wallet by 15th nov 2017 to clear your dues and avoid legal action. For clarifications, email us at [protected]@mobikwik.com.”

Please note that i had transferred said amount to pnb a/c no.[protected] of my relative. But system of mobikwik returned back the same amount to my wallet showing unsuccessful transaction. But on the other hand amount was successfully transferred to my relative's saving a/c.
I had never intention of cheating someone else or nor will be in future.
Anyhow, whenever i came to know payment is getting transferred to bank account despite failure message to me and returning the same in my wallet, i felt that that something wrong has happened and i immediately tried to contact on mobikwik's customer care. But their customer care numbers shown that these are being upgraded. Whenever, i tried to contact through email us link, then their system shown that this wallet account is disabled. Thereafter, i tried to load my wallet with this amount so that whenever they will come to know of this, they will be able to deduct the same from my wallet. But wallet was also disabled by them and i was again unable to load amount in wallet. Now, you can understand that what else could i do?
They never tried to contact me over phone or email regarding this issue despite they had all these details already with them.
Now, i contacted my relative in whose account amount was transferred, she told me that they have already taken a lien for the same amount of rs.8589.00 on her pnb bank account.
Thereafter, i have already loaded rs.8600/- in wallet on 11/11/2017 of which their system immediately deducted the said amount of rs.8589/- from wallet.
From the same date, i am regularaly emailing and contacting them over phone for clearing lien on my relative's pnb a/c no.[protected].
But they are not replying to any email and no satisfactory answer is being received over phone.
I have severally emailed them at their id's.
Mails id's are as below :
Sms recd. To contact on emaild id : [protected]@mobikwik.com
Lien created from email to pnb : [protected]@mobikwik.com
Customer support : [protected]@mobikwik.com
Please ask them to clear lien created by them on pnb a/c no.[protected] of ms. Rupinder gupta.
Hoping for a favorable reply.
