Cancel the deal

I bought a car from we buy cars PE branch, and I’ve collected the car on the 15th of June 2021 in one of the Gauteng’s branches. I have not received my car registration to date. I have inquired with your finance department and they referred me to the registration department. I have sent the numerous messages and even phoned them a couple of times but every time they request that I should give them more time and even promise to update me, but they never do unless I request an update. I think I have given them more than enough time, It’s been more than one month since I’ve collected the car. I have bought this car but I can’t use it because it’s not registered under my name. I don’t even have proof that the process to change the car to my name has been initiated, should the police stop me (and this is a risk I don’t want to take therefore I don’t drive it). I feel like I’ve parked a ****** car in my garage. Is there any way I can get out of this misery? Can you collect this car and cancel everything. If there’s a fee I need to pay, I’ll pay it. I’ll also go to the bank to cancel every thing before they start debiting my account. I’ll go to the bank this afternoon.
