Entry demands ...

Just had a man here saying he wanted access to our property to access a pole which is NOT on our property to install fibre for someone .. we have high crime lately and have been advised by our CPF to give NO-ONE access to your property ...so I said no ..he then said he would ask his boss to come and see me and within 2 minutes the boss was here .. demanding access... I refused and told him the said pole was not on my property .! He said they can get to the pole from my property ... I said no you can't come onto my property ..so he said ....well then I will simply cut your internet line and connect the new user .. And left... is this how people from companies treat other people ??? DISGUSTING !!!! I HOPE I GET A RESPONSE FROM OPENSERVE ABOUT THIS .. AS THIS IS ******** !!
