After several frustrating months and more emails than I can count .... and having got a bit of a resolution *not from Quickbooks but from a member in the community I might add, as to how to resolve the issue of uploading transactions from Barclaycard from a CSV file - it now seems that I can connect to Barclaycard. However, we have several credit cards and it is downloading all the transactions from all the cards into each card, rather than separating them into each card. This makes it a very difficult process to exclude transactions and going through line by line in each card - PLEASE ADVISE as to how to rectify this.
