Unprofessional and poor service

In April this year I paid up my account and requested it be closed. The in May I get a mail saying my account is in arears. So I contact them and ask whats going on as my account is paid up and should be closed and sent them all the POPs. To which I was then told they so sorry the account is indeed paid up and will be closed. On 16 July 2019 I get an sms to say my parcel will be delivered by dawn wing on 19 July, to which I respond and say I did not order any parcel and they need to cancel it urgently. I also sent a mail to them saying my account is cancelled and I did not order any parcel and they need to rectify this urgently. The parcel was delivered yesterday and no one from Isabella bothered to acknowledge my messages or emails and totally ignored the fact my account is closed and I do not want to receive their products any longer. Who gave them the right to activate my account without my permission!!!!!
