OP, i did receive the vouch copy from you but i received no further instructions on how to actually use it. Plus the coupon is expiring today apparently so I'm not sure what to do. Where should i go to redeem this?

I've tried to click upgrade storage on google drive but found nowhere to input the code.

Tried to pay via google play gift card and entered the code you gave me as well, but again it doesn't work.

Please send me a new code and clear instructions on how to use it, you can't just assume we know everything you know, lol.
