DKVG Attorneys - Not releasing ******** deducted occupation rent

We bought a property in Stellenbosch and DKVG Attorneys was elected to do the transfer of the property, We have been dealing with Marisa Koorts from the Belville branch, really not a great experience from day one, defiantly not willing to walk a mile, and defiantly not willing to walk an extra mile. The contract is very clear on the occupation dates, and yet Marisa have deducted R21k from the monies that was payable to us. I have been sending her emails requesting and demanding the payment as per the contract, she does not even bother to answer the emails. I will not recommend DKVG and defiantly never work with them in my life, really the worst conveyance attorneys I have worked with in my life!
