Bad service

I have a policy with clientele from 2017 that covers me and my grandmother. I don't receive any update since day 1 till today . I decided to cancel the policy last month hence the amount keeps on increasing without any communication. Firstly spoke to one of the lady from cancelation department and she told me she sent email for confirmation. Last week spoke to Brian who also confirm that email was sent but I have received any on my side Today spoke to Prega Khumalo who also confirms that she sent email to confirm the cancelation of the policy even now today the 10 of October am still not receiving any email from you I don't know is it because am terminating the contract or what !! I need that confirmation email for weiver period hence I have found a very reasonable amount to pay. If anything happens between me or my grandmother you will be reliable to pay me whether the policy is canceled or not coz from my new policy the need that confirmation letter so that I don't have to be on a waiting period with my grandmother

By the way both of my email and phone are working and I fail to understand why you agents keeps on saying the have sent email while on my side I don't receive any
