Cancellations and other things

Nice cover with chickenstamps and a frogstamp from Malaysia. Only the chickenstamps have cancellation, the frog stap did have a BIC cancellation/stripe. Do you have this problem often?

So now and then a postman/woman does find it necessary to destroy your stamps. Why ? I am not able to use the stamp in the Netherlands, also it has no gum. When the post in Malaysia is the blame, there it is also with now use, on a letter inside the country I can understand, but to make me unhappy.......Still a nice cover.
