POOR CUSTOMER SERVICES FOR NEW CLIENT

i installed a new alarm at my business end oct 22. I paid for the alarm by eft 26 oct 22 and emailed the POP to the sales person (Shane Stander), i used my name as reference, as ADT did not supply any reference or acc #. The alarm was installed. Today i get an ADT sms that my acc is in arrears, an OTP and bank acc to pay into. i was not sure if was a **** sms, so i called ADT customer services to enquire. The acc # on my ADT tax inv re installation was wrong. (EDW00562) They said my acc in arrears as they did not receive the R3 499 for the alarm. When i signed up, i asked for a copy of the contract that i signed, which ADT did not supply. I emailed Shane early Nov again requesting a copy of contract and he rep**** that he would email, of which today i have not received. THIS IS JUST BAD CUSTOMER SERVICES AND WASTING MY TIME, please advise if ADT agrees that this is poor customer services or is this how your company operates. I just hope that your armed response is not disorganised as your admin, if so then i am just wasting time with ADT.
