Cancellation hassles

I’m extremely frustrated with the service provided by finrite firstly I lost my phone on the 8th of August only for me to get the phone on the towards the end of the month which I had to go collect the phone from their offices myself because I couldn’t wait any longer for their delivery. I then spoke to Samantha H asking for advise for canceling the insurance as I’m not happy with their service on the 1st of September at exactly 19h58 I received an email from Samantha H stating that she can cancel the insurance for me I just need to give her the go ahead on the 2nd of September I sent the response giving her the go ahead to cancel the insurance and she didn’t bother to acknowledge and tell me the it’s cancelled I sent another email on the 14th of September asking her to please let me know if it’s indeed cancelled and I still got no response now to my surprise the premium is added on my Edgars statement I refuse to pay that amount. I would never recommend such a company to anyone they quick to debit but take forever to assist. I want the insurance cancelled and the premium reversed from my account.
