Well, I waited 2 days for setup because it seems I got into a new NL node. Mine is unmanaged since I think you are mentioning a manged service.
unrar no trouble, raring was painfully slow since the beginning, tried a few thing, os, programs, scripst, ultimately upgraded to see if it would do something, evidently upgraded believing in the 15 day money back, sure, they sate that they have the right not too, but also state if you are not fully satisfied they will refund you and then granted they consider it "valid".
10, 12 minutes minutes for raring a mere 2 to 4 gb file is not normal, it I was using any compression sure, but store mode?, I have a vps services with other providers, and while it its not done in seconds, it does not take that much time. I think this is reason valid enough, but apparently not and urged me to purchase more resources instead, which already did upgrading to silver.
Only that but enough for me to request a partial refund, I have no much issue in other aspects, not gonna lie to make the situation look more bad than it actually is.
Posting in a civic manner, this give an idea of what would be considered valid or not for a refund, since the "if we consider it valid" its pretty broad.
