Frontier Communications review: cable, tm & phone services

Over three years ago, Frontier took over Southern California Verizon Cable services. I started calling Frontier beginning in June of 2016 for services; however, Frontier falsely accused me of having a balance with Verizon 7 years ago! I think that what happened was that I order services from Verizon, but cancelled the order. Then Verizon stilled billed me internally in their system only. I never received a bill. But then when I called Frontier; I'm told I have a balance.
I have been trying to get my old 7 year old false Verizon balance to no avail. About 20 years ago; I had a similar incident with Verizon with cell phone service. I closed the accounts and disputed Verizon's false claim of not paying on time or that I owed. It took Verizon 5 years to clear me and sent a letter of apology to me, and have a copy.
I filed complaints against Frontier to clear my account. It finally was cleared on 06/2018. However; I still cannot have services with Frontier; since, it's retaliating on me. I tried it again last month because I'm moving and need to save on services. I placed two order; however, Frontier has red tagged me and will not honor my orders even though a representative too my orders at two separate times. I'm innocent and have 100% record of always making my payments on time. And last month my credit score was 758. It has come down a bit due to a current house purchase. Is there something I can do for Frontier illegally refusing services and costing me high prices due to such refusal! Even Frontier employees complaint about Frontier of such fraudulent treatment. I never experience anybody so bad doing business in Southern California. And when I filed a complaint they lied to the CFPB. And as a disabled senior citizen, Frontier is violating many of my citizens and consumer rights. Thank you.
