Sorry but we did not receive any of your earlier replies/emails - and we were unable to contact you by phone.
We did receive your email around 4 pm today but we did not get to process it before the end of working day. Our weekend duty is limited to emergency situations.
We can not delay the billing - our system for monthly payments is not setup for that and processing it manually is a big overhead.
You can re-upgrade your account at any time from Settings/Billing plan.
