It’s not the first time I have found my card being declined for purchases that I make regularly. Once again it was a case of the card issuer being too secure and blocking my transactions because they considered them to be unusual. This is all very well but has resulted in a number of regular transactions being cancelled. I now have to spend my time contacting the companies involved and making payment again by phone, something I tend not to do because it is not very secure. It does really defeat the object of having the credit card in the first place, I use it specifically so that if I should be compromised when making online purchases that my main bank account is not linked to it in any way but it only works if I am able to actually purchase items.
