I can't answer your specific question, but I have just had a similar experience.
I tried to re-contract BB and TV (Big Sport) on Saturday (1/4), where it was offering me Halo 3 at the price I was paying for Halo 1 prior to the 31 March price increase. But it wasn't allowing me to take the Big Sport offer at the same time - it was saying I had to wait for the BB order to complete on 4/4.
But then when I came to do the Big Sport order on 4/4 after my BB order had completed, it said that I had to renew my already renewed BB contract for a further 24 months starting 6/4 - so effectively adding another 2 days on to it!
Now, I know that's not really much of an issue, but it did just seem a bit odd, and I wonder what would have happened had I started with renewing the Big Sport package initially on 1/4 rather than the BB contract? Would that then have allowed me to renew both at the same time as I really wanted to do?
Either way, it not been the best customer experience.
And just to add to that, when placing the new TV order, I selected the option to receive a new BT TV Box Pro to replace my older model, which it said would arrive on or before 6/4 (and would incur a £30 connection fee). Well, it wasn't dispatched until late last night and Royal Mail has advised they will deliver it to me on Saturday 8/4!
But to be fair to BT, I contacted them about it and they have agreed to waive the £30 connection fee to compensate for not receiving the new box when promised (and at least I still have an old box to watch the sports channels on in the meantime).
