Worst Couriers

Good day. I am a seller on Bobshop and therefor use couriers almost every day. RAM Couriers want to charge for flyer bags. Every other courier, Internet Express, The Courier Guy, Fastway and Skynet supplies me with flyer bags for free. I do the couriers job by placing items in the flyer bags and having the parcel ready for collection and I bring business for the couriers. I have phoned RAM twice and they want me to pay for flyer bags. Bobshop chooses the couriers for sellers that they want to give business to. I would definitely not choose RAM ever.
