Bad communication and misleading

I was definitely buying a house from the seller directly and call him, meet him face to face, who referred me to a person that handled the renting of the same house previously, so I handed this Agent my documents as we stood together at the house, letting them both know I was definitely taking the house. The Agent was now the bridge between me and the seller. Then this Agent (Mpark property rentals) informs me she works through Betterbond. So the Offer to Purchase was signed and I submitted my documents, then the Agent gave Betterbond to start working with me.

I have a wife so I had to get her payslips too which cause a bit of a delay I know, cause she couldn't get some payslips as she works a rotating weekly shift and at times she doesn't see her HR department, also the HR was on leave during a time when we were getting information I did inform them.

So the offer to purchase was about to expire but the lady at Betterbond said she will speak to the Agent and get an extension on the OTP ...All and good I assumed the extension was granted by the fact that Betterbond continuing asking for my outstanding payslips and they went to the banks thereafter.

To my understanding I had not been informed I was never going to get the house or contact by this Agent or Betterbond, so once the banks had come back with an offer, I emailed Betterbond to processed.

I then got a call back on the same day that someone else has purchased the property on the same day that morning which I was unaware and uninformed of, which I had made plans to get a friend live at the house as they have sold their house to come live next door to me, which was the house I was purchasing.

I am upset that I was not informed or updated that the offer to purchase was not renewed and other offers they where processing with or I would have gone to the bank myself.

So I was misleading and didn't need to continue with trying to get the payslips or get the banks to proceed with processing the bond for me ...I was made a fall back plan and kept in the dark.

This is unacceptable and I am guessing they were just keeping me misinformed cause the Agent had my number to let me know the deal is off much earlier even Betterbond. Bad communication and misleading.
