Poor Customer Service and Late delivery

I placed an order on Monday 18th September. I qualified for free delivery if I wanted to receive the goods the following week. I chose to pay R35 to have my good delivered to a store of my choice in 2-3 days time. Today is the 22 September 4 days later and no delivery. I called the 21st September to find out where my package was and I was then emailed to say the courier would not deliver that day. No feedback on when I could expect it, no apology for the delay and not even an explanation as to why the delivery has surpassed its 3 day delivery period which is what I paid extra for. I called today (the morning 22 September) and was told I would get feedback. I called again at 13:00 and I am now being told I will recieve my package on the 26th September (9 days later). I have yet to receive an apology for the delay, any explanation as to why it is late or at least some sort of compensation for inconvenience caused. I selected the speedy delivery so that I could recieve the goods before the weekend which now will not happen. The option given was to recieve a voucher of the value of my goods and go to a store nearby to select the goods I chose so I can recieve it today, meaning I still receive no refund but I must go and pick and collect my own goods...Is this not defeating the whole purpose of ordering it online????? I asked to speak to a manager and clearly they were too busy to come to the phone. I am disgusted with this poor poor service!!! I am so disappointed and utterly shocked at the way this was handled.
