Wesbank absolutely useless - switching BANKS

I app**** for private finance online on 9 March, got no response and did a telephonic application on 7 April. Was told that finance was approved and received electronic confirmation. I was informed that a title guard would further facilitate the process. This was done, required documents were sent from both seller and buyer and this process continued for one month. Title guard noted that all was fine on 29 April and final signatures were required from the bank. On 4 May I received a telephone call from the bank stating that the application was declined due to bad debt written off, low credit score and late payments. Why was the application approved, a notification sent and not picked up right from the start - the response from the consultant was the above reasons and that this was referred to their legal dept. I informed her that I recently checked my credit score which was high and that I had recently done applications with other banks and the above issues never came up. This led me to believe that my profile had not been updated with Wesbank plus they were using an address I used 7 years ago. A waste of time and resources. Poor service. Regret ever dealing with Wesbank. Disgusted
