Time frame needed for the cancellation of purchased property and refund

Salam.

My developer has agreed to give me a refund after AED 50000 deduction. But my concern is that they say it might take a long time. They wrote we shall issue a cancellation agreement which needs to be executed by both parties.

On submission of the documents and RERA approvals on the cancellation and refund from the escrow account, the fund will be released and your name will be de-registered against the unit in Dubai Land Department.

The above process can take anywhere between 1-3 months in normal times which we are hoping to still be able to do that now but may expect delays up to 3-6 months due to COVID-19. Can you please confirm if this is the case?
