Disgusting service - depriving people of connectivity during the lockdown

Supersonic - you have no right to HIJACK a fibre line in a property that I own. You may have a dispute with the account holder (which I am not) but the account holder no longer stays at the property and now my new tenants are without connectivity during the lockdown. It has been a whole WEEK since I got a case number, provided you with the evidence that I own the property and this has still not been resolved. I have wasted HOURS of my time on your customer care line, only to be cut off. Your WhatsApp line is completely useless to me - as I am not even your customer.
