The most frustrating service I've ever experienced

Since having existing fibre re-connected via a number of different 'outsourced' partners (Vox do not have in-house service providers or technicians, they outsourced everything), we've had nothing but endless automated email responses to desperate queries for assistance, and a customer service hotline that never seems to work. I'm appalled! This outsource model is a failure if your different providers can't communicate with you, us or vice versa. Please can someone at least just return my calls? VOX ***
