Barclaycard has apologised after many of its customers who took out a credit card offer that was supposed to net them £100 in February failed to pay out.
American Express has boosted the introductory cashback rate on its Platinum credit card to 5%, matching the current best buy, the Capital One World Mastercard.
The owner of two major cashback websites is set to go bust meaning users won't get the majority of the hundreds of thousands of pounds they had collectively accrued.
