The same issue as all the myriad of complainants detailed below. 1% of reviewers recommending the company speaks for itself. All the terms & conditions are carefully worded to exploit innocent members of the public and the auto-renew facility is buried in dubious grey print and rather than require customers active acceptance is the default condition. It is blatantly obvious that Nova exists to fleece customers with total disregard for their satisfaction. It is abundantly clear that a well rehearsed and prepared defence exists for anyone complaining and that Nova is relying on stealth and deception to make money.
Avoid them like the plague. Quite how these people sleep at night defeats me.
