Payments made on the training platform are processed using Stripe, a leading and globally recognised payment clearing system and this allows us to accept payments from anywhere in the World. Credit cards may be rejected, refused or declined if they are limited only for use with national clearing banks rather than international.
You may call your bank and ask them to approve the charge to Cabling Science Limited OR ask them to allow International transactions, then you can try your card again in the training website's basket.
Alternatively, you can contact our Support team and discuss the potential of payment through a different means. Our Support team can be contacted through the 'Self Help' button found in the bottom right-hand side of the website.
