Getting Registration plates for my old car(Terrible)

My car is abt 6+ years old so had to book for the new HSRP accoeding to new guidelines. It has been frustrating to say the least. First I had booked an appointment for the 25th of January this year, called the dealer with whom the appointment was scheduled, here in Malad and they said well the plates were taken back by the vendor without informing us, so complained about this to the hell-pline number and they said well we will take a look into this and let you know. Few days go by, I receive a call from their senior saying they are still investigating the matter will update us. This went on for a few days I was busy back then, so I ignored this and directly called them on 4th Feb asking what is the update, they said oh the plates are at Borivali you will need to go there and get them installed. I said no, I had booked an appointment closer to malad for my convenience, on a date convenient to me, so please have this rescheduled, they say ok. More days fly by, and no update from them, I ca them and now they say I have to drop them an email, furious at first but then I immediately emailed them. Again, days go by and no update and now when I call the customer support they repeat the same shit that the plates are at borivali and get them fitted there. So I say ok give me the address And they even don't know what the address is? Wtf is this? What do I do going forward?
