Pathetic service and no response on review of Home loan

I app**** for a Home Loan on the 15 April 2019 with Prestige Banker Mafereka, Thuso. The bank requested information again which I have already submitted but I resubmitted to the Consultant that contacted me Mdunge, Lungile. She confirmed she received the documents and when I did a follow up she said it was with the Val department. Firstly the val department found that the builders rate was too low for the dwelling. I resubmitted once again amended documents. On the 23 May 2019 when I did the follow up again and again daily I was then told that there is a shortfall however credit will make the final decision. I called in and spoke to Celeste Bessit and she said it is still with credit. On the 3 June I did a follow up yet again and I got no reply. When I did another follow up Celeste then said the application was declined. I said ok but I got a revised payment so can they use the new payslip and she was sure no problem send me the new payslip and I will send the application back to credit for review. My husband was also in contact with Standardbank and also Spoke to Monique. Up until today I did not receive a response from Standardbank. I still do foloow up with Celeste and Monique and I got no response. I still wait the outcome of my standardbank home loan for the last 6 months. I will definately qualify for the home loan but standardbank has so pathetic communication s****s that 6 months later I'm still waiting for a response. With Standardbank been so imcompetent it has cost me alot of money. The seller otp has expired and he put the property on the market for a higher value. Please could someone respond. I am so frustrated waiting for an answer.
