Please refund me in full!

I wanted to rent a property in Pretoria. I made offer for the monthly rental amount, and the agent informed me that the landlord accepted the offer. The contract was then sent to me, but suddenly there were additional costs in the contract. I said to the agent that I do not accept that and he informed me that the landlord then says if I do not want the extra costs, then we should revert back to the original rental price and not the price that we agreed upon.

Leapfrom refunded my deposit but withheld R250 for admin costs & bank fees.

Eiher the landlord was dishonest and negotiated in bad faith or the agent did not give the correct information to me. Which ever way, the problem was not with me, but with either Leapfrog or their client, the landlord

Why should I pay R250 for bad faith negotiations or incorrect information from the agent.

I made contact with Silvana Dos Reis Marques - Pretoria East branch, and she is now not responding to me.
