Poor service from the beginning, mission impossible to cancel insurance

Firstly I made a claim on roof damage from a hailstorm, contractor came to inspect, sure no feedback for 2 months, I follow up, the feedback I get is the damage is due to non maintenance, asked for contacts to dispute this none the less never received the mail or any follow up, I decided to cancel due to poor service, in march already, its going into April now, Standard bank cannot even do a simple thing as cancel a **** service that I do not want, it's shocking how bad the standard of service is from this division, I've been paying 2 insurers for 3 months, best part is, Standard bank is deducting this fee from my home loan account, this fee is carrying interest, which in 10 years will be a considerable amount, I would never recommend Standard bank as an insurer
