********* and Unprofessional behaviour

I have received a parcel on the 05/08/2020 from Fedex Express. There was an amount of R316 outstanding for VAT & customs clearance. I have not received any communication with regards to an invoice which needs to be paid. Neither did Fedex call or email me regarding this. Today is 17/03/2022 and i get an email from a debt collection company that i owe funds with interest and penalties etc. This is highly unprofessional and unacceptable. I take pride in paying my accounts and every account of mine is uptodate. If i had been contacted to pay an invoice, then i would have done so immediately.
