Takes months for an AOD from your client to be approved so we can get our house

Bathong standard bank we bought a house and you offered us a home loan and so did other banks we den decided on chosing another bank not u now we have been waiting for over 2 months for you to approve the so called AOD from your client. Because of the lockdown buying a house has become a nightmare and the process has taken 10 months personaly I have never seen such a thing. I mean if you don't want your client to sell the house as their price then cancel the offer to purchase so we as buyers can go elsewhere. I feel because we did not accept the homeloan from you you are dragging your feet with our acquisition
