*** No Response

I logged onto my TFG profile to pay my account which is only due on the 1st of Oct 2021. To my surprise my card has been blocked Primary Card Number: *** Card blocked. I immediately sent an email to their customer service team to find out why ..... ***. Still no response - I have paid the account and 24 hours later the account is still blocked?? Please can i have some feedback on this matter.....
