complaint deluxe

I have had endless problems with this company. I have it all documented so there can be no mistake. They give you an invoice and you are expected TO PAY IN ADVANCE BEFORE ANYTHING WILL BE DONE AND THEY WILL NOT EVEN BOOK YOU A CALL!! come on, on even the contractors dont do that, they ask for a percentage and when that percentage is used up (follow by a checkable invoice) then you pay the next installment, but not ZONEWATCH - they want the whole lot up front!! not great especially if you have no come back if the work is not satisfactory!!. Also, on their invoice they do not state the account holder, it used to be Blatherwick t/a...., then it was Pinewatch, then it was Zonewatch, now, apparently its Zonewatch Public Safety. BUT THIS IS NOT MENTIONED IN THE BANKING DETAILS ON THE INVOICE IN THE DEDICATED BOX, so who knows, could be anyone!! Not impressed with this service. I have been with Blatherwick/Pinewatch/Zonewatch/Zonewatch Public Safety since 2000 - have always paid my dues on time but now they expect me to pay UPFRONT for a service that I don't know will work!!! come on.... who does that.
