Adt Security
Can't get hold of accounts!

I've been paying my account every month, 1st day of each month. Then my tenant sent an email to my agent stating that ADT phoned and said that I'm 3 months behind! I've been trying for two weeks to get hold of someone at Accounts. When I phone the switchboard number, they put me through to Technical!!! Don't they know how to operate a switchboard?
Maybe it is time to cancel ADT and get something else!!
