Netstar Very Poor Service

I sent Netstar an email on 01-04-2023 to terminate my contract with the company in line with (and 10 days before the required cancellation period of 20 days) of their contract Terms and Conditions. Today 03-05-2023 I receive a phone call from them, advising that, as I want tne contract terminated, that I will be charged a TERMINATION FEE, as I want immediate cancellation. I do admit that I lost my temper with the consultant, but that is the consequence of the person apparently not wishing acknowledge receipt of the 30 day termination request. I received an "auto-reply" from their system, advising that my email of 01-04-2023 had been READ, and that a consultant would contact me within 2 working days. This never occurred. Very poor Service - it appears that they will be only too happy to debit my account with the subscription amount, but are reclutant to comply with my request, so that they can dun a further amount from me.
