Selling my apartment was a long, ridiculously expensive and stressful process. I accepted the offer in November, and in January my mortgage switched to a variable rate. I thought it would only take a couple of months, cheaper than paying a fine. How wrong I was!

In any case, due to the lack of a lease plan and other difficulties, an act of amendments was drawn up. I signed it, the landowner's management company signed it, but it has been in the real estate management company since September 6. Almost six weeks! One guy delayed my sale for 6 weeks! The lawyer called and sent an email. I called and emailed. He sent a strange email in response, but now nothing.

Should I ask his supervisor to step in or register an official complaint, or will things go wrong for me? Will this lead to me being? I need to somehow escalate the situation in order to get the matter off the ground. I don't have 1,000 pounds. a month that I don't have for an empty apartment. These expenses also have no effect on the amount of my mortgage! So, am I being unreasonable, considering that 6 weeks is an unreasonable time to sign?
I'm completely desperate. Thank you in advance for any wisdom.
