Family Member Used My Info To Set Up Electricity, Racked Up Almost 1k In Debt And Continues To Use My Name, Ruining My Credit, Can I Dispute?

Located in Ohio, USA.

So like the title says, a family member with knowledge of my personal info set up an account with an electricity company using my name and racked up $949 in debt. I have tried disputing the collections claim the first time I saw it on my credit report, but all that happened was a drop in price from $950 to $949, they did not remove it from my account. The only proof I have that it was not my electricity account is the fact that I did not live with them when they set up the account. Since stating that in my last dispute, I assume that does not count as enough evidence. It's been about a year since I initially saw the collection on my credit but I haven't interacted with the collector company since I know that restarts "the clock" on it staying on my credit.

Last week, I received a letter in the mail from another collections company stating I owe hundreds to DirectTV.. I dont even use cable and my wifi is through Spectrum. This family member, however, does in fact use cable and switched from DirectTV to Spectrum TV after telling me it was too expensive. Luckily this one has yet to be added to my credit report yet, but this sure makes me mad beyond belief.

Is there any way for me to dispute these even though I'm lacking any written evidence? Any advice for saving my credit other than freezing it? All advice is welcome, thank you.
