No Communication and broken website

I phoned Standard Bank Insurance about 2 weeks ago to change the debit order details on my Insurance Policy. To date I have received no response on this request and I have no idea weather this was processed or not. The call centre just asked me to send en email, which I did and I told the support agent as much. She looked on the system and said that she will have someone action it. No one ever contacted me after this. No emails, no SMS, No phone call. I don't know how Standard Bank can operate like this with no communication to their clients. The only reason why I went with Standard Bank insurance, is because they were cheaper than my other company. If this is the level of service I get, I will definitely change it to another company, even if they are more expensive. What happens if I ever have a claim? Will they give me the same service? I also tried to update my contact details on their Insurance Website since they had contact details of mine that were more then 10 years old! I only joined Standard Bank Insurance last year, so I have no idea where they got the old information from. Anyway, trying to change it on their website also didn't work since their website gives an an error every time I try and update. Their Technical Support team has tried to resolve this, but until now they could not. If I ever get hold of them and get them to respond, I will most likely cancel my insurance with them. If they can't even operate a working website in 2020, then they are not the company to do business with in this digital age.
