Hey!
I have noticed a bug with 1.3.2 of Osclass Pay.
Explanation:-
First, i made a payment via Pay U money to make item premium for 1 week. and success and the period has been shown until when my listing will be premium.
But finally, when I have made payment to make same item premium for 1 day it showing me that my item will stay Premium until next day.
HERE I should suggest that plugin should make that item until next 8 days!
That is what I say Carry forwarding the days of premium services and I was able to regenerate that issue frequently.
Please see it with all premium services like Move to top and highlight etc.

Another suggestions...
2.) Mobile version should show Transaction id with the payment logs.
3.) Referral Credit should not be used for Orders. It should only work with premium services.

Thanks in advance!
