Horrible customer service and a ****

This company is a ****. Took out a policy with them in 2021, everything was fine until last year when my premium went up by 10%, which I was aware of. Was suppose to pay R243 but now they debit R598.11 and when I enquire about it, they say they'll call back. They haven't, instead they make excuses that I didn't reply, but there aren't any missed calls. They send me sms' saying my policy isabout to lapse sometimes sms' that my policy is in arears. How so when I've been double debitted for over 2 months

Tried calling them but you stay on the line for more than 10 min without assistance My aunt complains about the same thing, she even stopped paying them
