Object storage price confuse me


before few days I have created the first bucket on Object storage service and keep the bucket empty (0 files , 0 bytes).

The next day I noticed that the billing system calcuate a cost of 5€ for Storage (I attached a screen shot).
and while I’m in free tire mode (100€) they discount it . but the question is scaleway will bill me 5€ evey month for the that bucket (even it is empty) or what?




You can see the object storage pricing here:

The launch pack is billed at 5 euros per month and includes 500 GB of storage and 500 GB of transfer per Month.


So If I want to cancle the object storage pack to a void paying 5 EUR each month , what shoud I do?
