Agent did not see deal through

I recently purchased a home through one of the agents of Bakers Real Estate IN Centurion. The agent was initially very helpful but as we got closer to regsitration the attitude changed. Once the registration went through certain items on the snag list which were in the OTP were not handled. The seller refused to complete them and the agent in question passed the buck and eventually stopped responding to my messages fompletely. A month later and I am left sorting these items out myself. Bakers Real Estate has left a really bad taste in my mouth.
