Santam, insurance bad and improper

So I changed banks, sent an email with proof of new banking details to Santam to notify tbem of the change. 2 months later i get an email saying my insurance has been suspended because they couldn't debit my account. I call to check what's going on. They say perhaps my account number or branch number is wrong. They say they will reinstate if i so wish. I say Yes please and reconfirm my banking details by mannerbof emailubg a letter from the bank. Come month end... No debit from them. Why, they are having difficulty debit my account. Why, they dont know. They said they will investigate and come back to me. 7 days later, no phone call. Instead i get an email saying that my case has been closed! I respobd by asking how was it resolved, do they know why the couldnt deduct premium, theycrespond and say my case is closed. In 2 days, my insurance was goibg to lapse again because for 4 months they failed to collect premiums. What's that? When i call, the lady who first tried to assist me said, they were supposed to tell me yo deposit the premiums while they are investigating, nlah blah blah... More than a week later... Sorry, I quit.
