Pronet Did Not Cancel My Membership or Remove Equipment Before I Moved Out

We are moving out of Istanbul and trying to cancel our Pronet membership while requesting the removal of their equipment. Despite calling customer service every day and spending hours on the phone, nothing has been resolved. We only have one day left to access the old house, which is a rented apartment. Tomorrow morning, we have a flight, and there is still no solution. I have no idea what will happen to their equipment, and this situation is causing a lot of stress. There is no resolution and no one to address the problem, even though we have made payments and are willing to pay any additional fees required to cancel the membership. We urgently need technical service to remove the Pronet equipment.
