Credits removed after new card added to account

Hi There,

I tried the chat which did not help as they had no idea and said someone would look into it.

But essentially what has happened is my card has expired so I added a new one under Plans & Products > Edit Payment Details.

Now it shows I only have 10 credits when there should be 102 since I have used 28 credits and had the plan active since May 2016.

I obviously did not cancel and do not want to as this would mean losing what I have payed for.

What do I do next?

Kind regards,

Jason
