upgrade

I don't have any credit card and paypall account, how can I upgrade my member. Thank you

You can ask someone else to pay for your membership.

Give me your bank details (Please don't ever give anyone your bank details! - Staff)

I don't remember them.

I was talking to the OP

I assumed so, but... just in case.

If I upgrade my  membership, how is it with my vacation? Is it  plus 30 days? Every year, or just once?

To my knowledge you don't get a new bank of vacation but begin accruing new vacation days at the rate of the membership level; 3 days a month for gold and 5 days for platinum/diamod.

Thank youfor the explanation, but it is in fact only one day more a month. Now I have two days a month.

It is then +50% more days a month for gold, and no less than +150% more days a month for platinum/diamond.

Understand, +3 days a month, instead of 2 days.
