LazyPay — I have 1500+ extra amount in my lazypay account

I payed 3009 to act fibernet using lazypay.
After a month I had a bill of 3500 which I payed..
That I used lazypay for a month amounting to 1500 something and I got my 3009 refunded from act fibernet..
So I have extra 1500 in my lazypay account which is displayed in my account, but I am not able to use lazypay anywhere.
So basically lazypay owes me 1400 something that I am not able to use
