INABILITY TO CLOSE SPORTSCENE ACCOUNT

In December 2020 my Sportscene account was blocked. When I enquired this, Customer Services told me that too many purchases was made on my account and they thought it might be *****elent-firts time I heard about something like this. Last weel I decided yo pay up this account and went into the store to have it closed. I was then told the account cannot be closed seeing that it was blocked. Could`nt assist and the next day went to another Sportscene branch who eventually succeeded in unblocking my account. When I told the Shop Assistant that I want to close the account, it was again blocked. Apperently till the 13th , dont know why. Tried contacting them via e-mails, but you only get automated responses back. Why is it so difficult to close your account. and why must it first be blocked. Another thing, my account has never been in arrears.
