Failure to Clear / Return my money

There’s been uncleared transactions due to authorisation hold and it has not been returned to my account. There’s amount dating from May , June and last Wednesday July 16 which I thought would be cleared within 3-5 working days. I called multiple times and was told to send an email , which I’ve done 3 times with no response.I’ve been banking with absa for years and I’m encountering this problem for the first time without getting any sort of solution from them. I just want my money back
