Not that this helps your situation at all Osc
but when we were buying this house the owners were having problems getting the owners of their new house to close the deal..the upshot was we stood to nearly lose this house which we absolutely didn't want to happen.
Anyway..off I go into the estate agents office for a good old moan.
These were the days when smoking was done in banks, buildings, etc and the female estate agent was sitting there chuffing away on her fag when I was having a rant.
Her response???!! I swear on all I hold dear this was her response:
Oh sit down and have a sweet!!! And promptly offered me a sweet from the little glass bowl on her desk!
Said sweets were then threatened to be shoved up her ar*e if she didn't sort this out now was my response!!
We signed within 48 hours.
