annoyed and upset with tfg online

I placed an online order for a pair of sneakers on the 30th January and was charged for express delivery. A week later I still never received the parcel. I phoned on the 5th February to be told that its normal delivery and should wait until the next day because its with the couriers for delivery for the following day. so the next day ......still nothing. I check the online to see where the parcel is and it still reflect with courier. so I phoned again and I'm told that they have to contact the despatch because the parcel should've been delivered 2 days after I placed the order because I selected express delivery. I was promised that they would phone me back. .......and nothing. I phone the next day and I'm told that they cant locate my parcel. it's lost. sorry for the inconvenience....and that's it!! I get the item credited off my account but I'm told that they cannot credit me the delivery charges!!!! So am I supposed to pay delivery charges for something I didn't receive!!! that's just *****ery. if they did that to 100 a day imagine how much money they would make by charging people delivery fees even though the item wasn't delivered. I want my money back for the delivery charges.......and be compensated for the inconvenience of losing my order in the first place!!! I actually ordered the item for my daughters birthday. I am so frustrated and annoyed that company's can do this to their loyal customers!!!!
