You are legally entitled to a refund. Since there is no written clause stating the security deposit is non-refundable, and since the pitch deck does not mention non-refundability, the company cannot legally retain your money. Under Indian contract law, the burden lies entirely on them to prove that the deposit was meant to be non-refundable. In the absence of any written term to that effect, the default rule is that all advance payments are refundable if the contract is not finalized.
Your situation is strengthened by the fact that no franchise agreement has been executed. Until a formal contract is signed, there is no concluded contract between you and them, and any money taken must be returned under Section 65 of the Indian Contract Act (benefit received without a valid contract must be restored). Their claim that they “spent time and resources” has no legal value, because no written agreement exists which authorizes them to charge you for consultations or discussions. Preliminary franchise conversations do not give them the right to retain a deposit.
You can absolutely send a legal notice demanding a refund. A legal notice is fully justified and in fact recommended, because their refusal constitutes both misrepresentation and an unfair trade practice under the Consumer Protection Act. Even if there is no written promise of refund, the key point is that there is no written clause of non-refundability, and the company cannot impose such a term retrospectively. In similar franchise disputes, consumer courts consistently order companies to refund the entire deposit along with interest and compensation.
There is nothing stopping you from sending a legal notice even today. If they still refuse, you can file an online consumer complaint and seek a refund, interest, and compensation for harassment. You have a strong case for recovery.
