Account update

I app**** for a loan with Capfin, they called me on a Saturday and I went through the vetting process for about 20min. They then sent me an sms on Monday that my loan was approved and the money will make its way to my account the following day. I then called them to cancel the loan coz I did not need the money anymore, my weekend emergency was long gone. They said they cannot stop the payment as it is already done, they gave me an account number and said I should payback the money as soon as it reflects on my account.

The money reflected on Tuesday, I paid it back same time to the account number that was provided. I got an email that they had received the payment, but they have failed to update the details on Transunion. On my credit profile it still shows that I owe them money and I have been sent from post to pillar, trying to get them to update my credit profile.

Can this please be sorted out ASAP.
