Travel Insurance Claim - No acknowledgement for claim submitted received

My husband submitted a Travel Insurance claim 27 May 2022. He tried to call to get confirmation of receipt for the claim. Holding for so long just to hear reply "we are experiencing high call volumes" He also sent e-mail on "Contact Us" Explaining that he want confirmation that his claim was received. No one has called or contacted him or he has not received any e-mail as yet as confirmation of his travel claim that was submitted. This is totally unacceptable, surely not what should be expected from such a big company. Please advise and contact my husband otherwise there is no choice other as to refer this to the Ombud for Insurance. Surely his claim should have been logged by now and a reference should have been sent? As Absa Visa card holder this was the choice I was given by Absa. We await your reply
