I am seeking assistance to change back to subscription plan. I have not used mudfish in a while and did an oopsie. I rather not wait the full month. I realise that pay per traffic is draining much faster than I thought but speed wise, the subscription model fits my needs better. Could I get a 1-time curtsey switch to subscription model?
No problem. 
I’d changed your data plan to Subscription and reset your changeable date too. If you’d like to change it back I think you can do again.
