"Poor customer service"

This reviewed is based on extremely poor customer service from the customer service team at Blackheath hospital. My elderly father is a patient at Blackheath hospital and on several occasions reception had sent us to the wrong address. We were sent to Lee Terrace for ECG and sent to Independent Road for blood glucose test. My father has bad leg so we had to call taxis back and forth. We also met another patient at Lee Terrace who was wrongly sent there so I offered them a ride in my taxi as his wife was in pain and had booked to see a doctor in Urgent care but was sent to the wrong address. Another incidence happened today when I called to booked a follow up appointment for my Dad in GP service. I spoke with a person in the GP service and they told me I can book the appointment but can't call to change or cancel the appointment. I explained to that this has never been a problem because my dad is deaf and wears hearing aids and I am responsible for all his appointments. They still insisted I can't call to cancel if the need arises and that I will still be charged. I don't normally write reviews but the customer service at Blackheath hospital from the reception and those that take the bookings for appointments is extremely poor. This is a private hospital and I except better. I would be grateful if this matter is looked into.
