I'm sorry you found the appointment stressful, must be even more so at the moment given you can't have anyone with you for support. I assume that there is another member of staff in the room though, such as a midwife?
I'm not sure about c sections as I didn't have one, but what I do know is that there will be LOTS of people in the room (10-15) so even if the consultant does happen to be there, you won't be "alone" in the room, if that makes sense. From speaking to friends who have had planned c sections, it seems that you just get whoever is on "c section duty" on the day but this is something that you should definitely ask about and may likely be told anyway.
I don't know what TOP is, sorry, although from the context I assume it must be a form of counselling or support? (Google hasn't been very helpful, sorry!) If you don't want it then you just need to be clear at the next appointment - perhaps as soon as you enter the room you just state "I don't want TOP, thank you very much for the offer and I won't be discussing this again" or have it written at the top of your notes.
It's good to hear that your baby is healthy, how many weeks are you? Is your consultant related to the high risk or the c section? As I don't think my consultant performed c sections (she originally proposed that I have a planned one, which I didn't want) which is why she said I should have an appointment with someone else to discuss pain relief, so maybe it's a similar thing here?
