One minute the Home loan is approved, the next minute its not

Made an application for a home loan with standard bank as i bank with them. received a reference they gave me a pre approval and arranged for assessor to view the property. Assessor viewed the property on 07th of april and i was told on the 8th of April it was approved and was sent the Quotation to accept. i accepted on the 9th of April and received an SMS confirming i had accepted the offer and attorneys would be notified. i hadnt heard any thing since so decided to do a follow up on tuesday the 14th of April only for me to be told the Home loan had been declined. i was not notified on mail, no sms or phone calls advising me and here i am preparing to begin the process of getting everything i needed for the home only fo this to happen. it was only the following day on the 15th i managed to get through to someone who advise me the home loan was declined based off the property approved plans not being registered at the title deeds office which i was not informed off what could be done about it or whether the sellers could do anything that could change this. and up until now i have received no communication in writing on the reasons it was declined which i not only find unprofessional but disrespectful. even the so called "assigned" banker who i sent an email asking for assistance has not responded since. even though they gave me very competitive interest rate i will be taking my business elsewhere in view of the way they seem to disregard communication on their whim and fancy, i actually am considering changing my account to where i will actually get feedback and assistance when its needed. highly frustrated that this has left a sour taste in the mouth with the experience received
