Additional Charges for what?

so my wife and i decided to get armed response and alarm installed through ADT.<br> it seems this was a mistake. on installation i was advised to call the call centre and ask about a lock for my gate so they have access to my property in an emergency. so i called and spoke to a lady who then sent a guard to me. he said he will be in touch to let me know. 3 weeks later, i called again and they lady who i got through to sent another guard and went through the same procedure. still nothing.<br> after another month i called and said i need to get this resolved. i was told by the installer that this would be covered. little to my knowledge i was shocked it was not true. i was told by the operations manager for my area that the lock costs R291 ex VAT and it will be added to my bill for the next month. i said what the hell is in that lock that makes it so expensive??? his response \everyone is buying it so you must too"i said i am not everyone and want to know why this \""lock\"" is so expensive and why i must pay for it!!! he then put the phone down on me. is this how you treat new customers??? hate to know how you treat old customers!!!!"""
