On Dot Courier — not even a single phone number is working and i cannot track my courier

I have not received my courier yet. It was dispatched from faridabad to thane on 4th august 2020 and today it's 10 august 2020, no information of my courier. I cannot track my parcel with consignment number, i also sent an email but no response, also i called on several landline and mobile number of on dot customer care but all the numbers are invalid. If you guys cannot follow the procedures then why you have opened a courier facility/services. Kindly shut down your company and allow other companies to work.
