Worst Service i have ever used

So i bought a pair of CONVERSE online from Markham on the 19th of December. I received my invoice and got a email that said that they will send me an sms once i can collect at the store (takes 3 - 5 working days). on the 4th of Jan i Call in to ask about my package and i was told that according to the system it shows that the packet was collected. The call Center agent then told me that he will have to get a slip from the store to see who signed for it and and he will get back to me. On the 9th of Jan 2018 i get a call followed by an sms saying that i can come collect the item in store. When i got there the cashier opened the packages and saw that it was REEBOK and NOT my converse iv paid for. I requested she send the package back and she put me through to the call center agent who advised me that they will collect the item the next day and it will take 3-7 working days to process and 7-10 days for my money to be deposited back into my account. On the 22nd of Jan 2018 i call TFG to follow u on my refund and i am told that the item was only logged for collection on the 19th of January 2018 and the item is still in store, they are waiting on the courier to collect it from the store. The lady advised me i will have to wait ANOTHER 3-7 working days for this to be processed and then ANOTHER 7-10 working days for my money to be deposited. I am very unhappy with the service, as online shopping was suppose to make it easier and more pleasant to shop, but this has just become a nightmare. Here i am nearly a month later, without my converse or my money.I am a very unhappy customer and will never shop online from TFG again!!
