Request for cancellation of subscription.

I sent an e-mail on the 21 st of June 2017 , requesting that my Netstar Go subscription be cancelled , I received the following response on the sane day , "Your request has been logged. One of our service champions will contact you within the 30 day notice period to process your request. Reference Number: ********** 43 " It is now the 30 August 2017 and no communication at all , I will definitely not recommend their services to other people , I am disappointed in the feed back , yet my subscriptions got payed on time every month.
