Disappointed First Time Customer

I am extremely disappointed by the service I received from the TFG online store. I placed an express order for the first time yesterday. At 3pm i decided to give the call centre a call to follow up. The agent was not helpful. All she told me were things I knew already. I told her that I urgently needed the item and had opted for express and if there was anyway she could assist by following up with the courier. She said no and that my parcel MAY be delivered by Monday but she was not sure. I then tried to follow up myself using the tracking number provided. From previous online shopping I knew that any OCT numbers could be tracked via 'On the dot' and from their site I could see that dawn wing was the courier. Once on the dawn wing site, I got no result. I was given the incorrect tracking number! I then called dawn wing, and they let me know that TFG had booked economy and not the express service. It was so ridiculous and disappointing at that point since I had opted for express. It has just been one let down after another. I will most certainly NEVER purchase from this online store again. Disgusted!
