Terrible Customer Service!!!

Good evening. I would like to file an official complaint about your service which is up to maggots!!!! I have tried changing my account details on more than one occassion online with no success. Then for the first time in October I get an invoice and paid said invoice on the 11th already in full!!!! I tried testing my unit tonight and was told my account is with pre legal and my unit cant be tested. How is this customer service??? I have also on the 11th sent netstar an email and have not had any reply to date? I expect a call back on *** and better service. At no time did I refuse to pay my account!!!!!!! At no time did I willfully negate on my commitment to pay for the service!!! This is terrible service and it has been from the beginning in struggling to get the unit fitted!!! I am furious. Customer service my backside!!!! Your company will not bring my name into disrepute because you can't deliver efficient customer service!!!!
