Debt collection fee after debt has been settled

Debt collection fee after I have settled my account doesn’t make sense to me, I settled the account on the 15th July 2025 only to receive a statement in August showing debt collection fee for the 16th ?? What debt because I’ve paid what was due make it make sense and it not the 1st time this happens, so I’m being punished for settling the debt I had, now that is strange

The account was not yet handed over maybe I would understand but I had sent an email to Bellbouy that I will pay by August and I paid up in July.

Bellbouy needs to do better, if they felt there was a fee needed to be paid they should have called me before or after making payments, this is a reap off…I don’t even appreciate getting sms because they charge for them, a statement alone is enough because it shows all the details
