Beyond belief the cancelation processes.

Cancelled contract via website (28 March 2020). Consultant called to confirm(1 April 2020). They sent an email to confirm cancellation(1 April 2020). It is nearly 2021 and I am still being billed. For a service I never used. Called in at least twice a month for status of cancellation. And was told today! the contract was never cancelled(14 December). Here is a "sorry" even though all the proof is there, I now have to re-cancel it and settle the account as if I am leaving the contract early. Dear lord give me strength.
