FNB connect ******** customers

I had ordered a macbook with FNB connect, I was eventually sent an sms with a promise that the package will be delivered on the 17th May 2019 between 9am and 5pm, I waited the whole day for the package to arrive, I even called your digitalplanet call centre numerously enquiring about the location of the courier. I have never experienced such incompetence and unprofessional service in my life. After realising that I was not going to receive the package I immediately sent an email requesting that you cancel my order effectively and immediately. Now I am receiving an sms that says they tried to deliver but could not find me and I will liable for delivery costs. I dare you to try and deduct any money in my account then there will be hell to pay, if there courier was there why didn't the try to call me? like any other professional couriers would normally do, or is this your way of forcing customers to pay for the delivery? cancel my order immediately or I am cancelling my account with FNB and also moving my home loan to a bank that knows how to treat its clients.
