No, I never received a call. Sadly that didn't surprise me, given the overall experience I've had with the customer service from TalkTalk.
I tried engaging via Facebook messenger after a few days and then called again. They told me similar to you, that sometimes the online orders fail, and that that had probably happened to mine.
What I think is pretty terrible though, is that if this is obviously a known problem, there's no 'safety net' to check for failed orders... If I hadn't been proactive in chasing the order confirmation, I'd have been sat in my house this afternoon waiting for an engineer that was never going to come. (I've seen stories of this happening on these forums).
What I should also add, is that because TalkTalk ran a credit check on me, and I subsequently did not get a product from them, it will look to future companies checking my credit like I failed the credit check with TalkTalk. So this will likely have an effect on my future credit applications.
I guess there's a chance that the order failed due to me failing the credit check, but my score is very high (999/999 on one agency, 700/710 on another) so that's unlikely. But again, surely TalkTalk should have a process in place to notify customers if there order had failed for that reason?!
Anyway, this experience was enough for me to lose confidence in TalkTalk and renew my offer with sky, albeit for a slightly higher monthly fee. It's a shame, because the TalkTalk product does look good, and the price is very attractive, but if the customer service basics are not in place I think you will continue to lose orders
