BAD SERVICE NO FEEDBACK STAFF ABSOLUTELY CLUELESS

After numerous attempts on hello Peter my dispute regarding unpaid duties remain unresolved. I paid excessive duties in Dec. Current order is for items reordered on credit passed by supplier. As I already paid duties on the same items I refuse to pay again. Obviously the staff are not trained for manual intervention. You are referred to a BOT who does not give you the option to resolve issue. Told by staff to send proof of payment to the number which is the BOT who obviously does not accept images. Buffalo certainly does not care. Staff are clueless and have no idea to resolve the issue. You are sent from pillar to post, spending hours on phone at your expense. Trying to email service@buffalo redirects you the the silly BOT!! Then Buffalo decided to ship parcel to SA. Currently at AIR DC since 1 Jan with unpaid duties. I AM NOT PAYING, what happens now. I am still receiving msgs of unpaid duties.
