Why don't you have a bit of fun with her.

Dear Amela, As you are only fairly new to ebay and from the looks of your feedback you seem to be having a lot of trouble receiving your items. I am going to take it upon myself to have ebay check your account and will also contact canadian post and inform them that you are not receiving your parcels. They will check out whether you have a dishonest postie in your area or whether it is just sheer coincidence that all your parcels are going missing. No need to thank me for my troubles I understand ebay can be a very difficult place to buy from and there are many scamming sellers here. (or similar)
