I am afraid my experience with Top Cashback was not particularly positive.
I clicked through to a site hoping to earn a large amount of cashback, I completed all steps required to qualify for the cashback, but alas it did not track.
I then had to start a claim for missing cashback, but after waiting a good few months I was told my claim had been rejected,
I realise the site stated that cashback is not guaranteed, but when you do everything correctly, and the missing cashback was £60, then it stings a little.
It felt like Top Cashback weren't really on my side, and didn't care too much that I had missed out through no fault of my own.
