Consultants not doing their jobs!!!!!

I called 3 times today to give notice to cancel my contract. The first time I spoke to Andrew who said he was processing the cancellation and then the call cut and he didn't bother to call back. I then called back shortly thereafter, and was told that the cancellation is not reflecting yet and I should call back an hour later. I called back 4 hours later and still the cancellation does not reflect. I am so sick of having to call and listen to the voice prompts again and again. Can my contract for *** be cancelled please so that the last date of the contract is the 30 October 2022!!!
