I have one oxy and one argon bottle on account but actually have a few more bottles not on account . BOC now have a new ID plastic tag on the neck of the bottles . Most of mine don’t have this . When I took one to BOC to exchange it for a full one I was told that was not the bottle you received from us last time . How am I to over come this problem of getting my bottles filled without paying more bottle rents per year . Does any one have the same problem or the solution
