Terrible Service

Ordered x2 items 07/05/2020. I received communication one item was out on delivery 19/05/2020. When viewing the website it stated the item arrived 19/05/2020, I went to collect the item but they needed a code for collection, I tried on 3 separate occasions taking every form of code received. I contacted Pargo as per the email sent from TFG, whom told me they are not handling the order and directed me back to TFG. I finally managed to contact TFG to which they told me the parcel has been sent back to the warehouse due to non collection (26/05/2020). Which is not 8 days as per their communication and the consultant I dealt with also said it is weird it has already been sent back, and I find this very strange after trying to collect on 3 occasions. Please can this be rectified as I do not believe it is my responsibility to reorder the product and TFG has not upheld their promises, and I was patient for delivery in the first place. It is 26/05/2020 and the second item still shows as at the warehouse.
