Bad service Absa bank

I submit a claim to Absa in April to the claim department where I can claim for loss of income which I did with all relevant documents as well as letter from employer stating that they could only pay a percentage of my salary as they have not been paid by Prasa. They then pay the other half in in April. Now Absa said my claim is invalid as I did receive salary/income in April which I totally deny and if they have read the letter from the employer properly they would have picked it up. I am currently busy with my union to settle this and also a false announcement from the company that they claimed for us but government rejected it that's also false. Now Absa said they going ta send my claim in for re-evaluation and it will take another 45 days. Is this how they treat me that's for decades there client. Total *******. They have in all the time they assest my claim not once contacted me for any communication. Pathetic
