Random SIM card charge when upgrading devices

So this may be nitpicking but I thought it was enough of an issue that I should forewarn everyone here.

I recently upgraded to a Note 8 on my account. At the store, I specifically said I wanted to keep my old SIM card, and no SIM swap was completed when I picked up the phone.

Lo and behold, on my new invoice, I receive a SIM card charge. I find this both amusing and sad that this is automatically charged to customer accounts even if no such service was provided. Perhaps they aren't too far away from Rogers and Bell, what with all the news regarding those two carriers that is emerging.
