Atrocious Service!!!

I have never seen and experienced such atrocious service in my life! It’s been more than two weeks now since I sent an email to Absa Activate Insurance Company to cancel my insurance. I have been calling them everyday, and I have been put on hold on the call for more than 30 minutes, without anyone from the company answering my calls. How can the ABSA Activate call center experience high volumes everyday from 8:00am until 4:00pm? The company does not answer calls, respond to emails, and on top of that their app is totally useless. How can a brand as large as ABSA be associated with such atrocious services? They continue to debit my account even though I have sent numerous emails and tried to call them to cancel. No man! this is unacceptable, *******, and abusive... Can someone please help me?
