Topcashback Tracking/Click issues

[mx5bitz_uk]

Not sure what is going on with my Topcashback tracking at the moment but have quite a few issues especially with Ebay. Usually a claim sorts these out eventually but on 8th June all went completely pear shaped.
As usual I signed on to a separate Internet Explorer session reserved for ebay purchases through TCB. Bought an item early in the day that tracked quickly and left the session open. TCB upped ebay cashback to 5% later that day so I made a couple of offers on two more items. Went back into my IE session and bought the items when the offers were accepted. These were through a different ebay ID, so signed out of the first one and into the other before paying.
No tracking and no click through, so when I tried to make a claim only the first, tracked transaction showed - no clicks for the other two. Amount involved is about a fiver but TCB say as there is no click recorded they cannot help.
Hopefully only me struggling with this?
