Dead. Silence.

I have been chasing Vodacom since 25 May 20 to revert to me in regard to: To Whom It May Concern, Please kindly cancel with immediate effect the contract for THE OAKS HOTEL (PTY) LTD, cell number ***, account number B***-0, which expires on 1st June 2020. It will be appreciated if this number can be converted to Pay-As-You-Go.

But with no response, despite having emailed, called the call centre a few times... Does Vodacom not want to retain customers? Please revert to me asap. Thank you.
