Refusal to cancel service

One star, only becsuse I had to select something - I app**** for a subscription with Home-Connect on 12 June this year, and notified them on 16 June that I want to cancel due to a change in circumstances. Despite the fact that I have made numerous attempts to cancel, my account is still being debited and they refuse to cancel the service. They have debited my account every month, with varying amounts, despite my explicit statement that they do not have authority to debit my account. I have not accepted a debi check mandate from them (nevervreceived a request) yet they continue to debit my account. This company has no regard for client service or consumer rights, stay away!!!!!!
