TA, in-a-mess, the message that should be going to those thinking of entering an IVA is to research, and then research some more. If they read my comments about how nigh on impossible it is to speak to an IP, they need only to read around the forum to find those IP's who DO communicate.
As we have seen, nudging requests higher does not usually help. Some firms have an active policy NOT to allow us mere mortals near IP's (like the doctor's receptionists of old). If you are one of the thousands of clients with the firm formerly known as CSSVA, getting hold of their one and only IP will be difficult to say the least!
I feel that ease of access to an IP, or otherwise, is a crucial consideration in choosing a firm to represent you.
In-a-mess ..... I have had no cause, yet, to speak to my IP at GT. I was just imported there from RSM, where I chatted to an IP regularly. Should the need arise and I get no joy I will be mentioning it, never fear

My opinions are merely that .. opinions based on experience. Always seek professional advice.
