Discovery ******* insurance

Got a whatsapp a few days before debit order that my premium is double what i usually paid! When i contacted them after struggling for a while with the website chat that keeps on kicking you out, i was told i received an email informing me of the increase and i had to accept same. I never received said email or confirmed any increas. They don't call you back when requested and have a million excuses regarding your membership. Bonitas will be receiving my support after they are done *****ing the last of my money.
