Shocking online services

I'm so disappointed with the online service I received from TFG. I placed an order for 3 items on 22 Dec to be collected at Totalsports The Glen Shopping Mall. The order was delivered in drips and drabs, I had to make 3 seperate trips to the store to collect my order. When the third parcel finally arrived, I noticed that they had given me two left shoes!!!! I now have to make another trip to get my refund! The staff clearly don't check before it's sent with the courier.. Online shopping is supposed to be convenient, this experience was an absolute nightmare. There's no excuse for bad service. Don't think I'll use it again.
