Standard bank VERY POOR RESPONSE

I have been experiencing difficulties with Standard bank card division and SIL insurance. the former has blocked me trying to pay with my credit card online . I need to rely on online as I have a comorbidity. two people cut the call and I have sent numerous emails and have had no response. I paid off my homeloan in the middle of February and I have wanted to continue with the insurance. since the middle of February I have had 2 emails response telling me they will contact me. NO-ONE HAS CONTACTED ME FOR OVER A MONTH. Today I requested a call back this morning to discuss these complaints and resolve it so that I can use my card online(it is in credit) and to have my home insured(it hasnt been insured for over a month BECAUSE OF STANDARD BANK. No response to my request for a call back today. I am seriously thinking of moving banks even though I have been with Standard bank since the 80's this is COMPLETELY UNACCEPTABLE BEHAVIOUR!!!!!!!!!
