Unreliable and unreachable

I have been trying to reach Finrite to cancel my policy with them for over 3 weeks now.. each time I’ve had to hold for over an hour without getting any assistance besides the recorded voice telling me I’m a valued customer and that my call is important to them.. (Lies) Does anyone actually work at Finrite? My 2 year cellphone contract ended with Telkom so I upgraded to another phone, but was told I had to call and cancel the policy for the previous cellphone.

What now? Will they respond if I send an email or what? I’m not going to be paying insurance for a cellphone I’m not using.
