We bought a house a couple of months ago - completed in mid June. Our conveyancer was a PITA the entire process (slow to respond to emails, gave conflicting advice, never answered her phone...) but we got there in the end. The day before we completed we paid all monies owed including £695 in conveyancing fees and the stamp duty on the property which would be paid on our behalf by the solicitors.
A month after completing my DH got a letter from HMRC to say the stamp duty hadn't been paid. His name was on the HMRC letter as Purchaser 1. Purchaser 2's name is blank 
I contacted the solicitors immediately by email and an assistant phoned to advice that they'd contacted several other customers but unfortunately we'd got our letter before they contacted us- several payments of stamp duty had been made but with the wrong reference meaning the payment hadn't been attributed to our purchase. I was told it would be sorted immediately and to ignore the letter. I questioned why my name wasn't on the tax demand (I put in all the money for deposit from an inheritance so I was a bit worried I didn't actually own the house!) - apparently this is normal. I was cross that a) they hadn't bothered to contact us and b) they'd cocked up something so simple but I thought nothing more of it.
Yesterday DH received another letter from HMRC - they now want the stamp duty plus interest as apparently it's still not been paid. I'm fuming and now worried that she's cocked up elsewhere in the conveyancing and the reason I don't appear on the tax demand is because I don't actually own it (although I am paying the mortgage)!
I've emailed the solicitors and if I haven't had a response in writing by Monday lunchtime I will paying them a visit on Monday afternoon.
I know that solicitors are expensive but I really feel I've paid £695 for bugger all (we paid extra for the searches!)and I'm still having to send emails, chase up paperwork 2 months after we completed.
WIBU to demand a refund, at least partially, of our conveyancing fees?
