North Texas Tollway Authority [NTTA] review: Web maintenance / unable to load toll tag

The toll tag users of NTTA has been unable to reach customer service to load our toll tag due to web maintenance, circumstances due to ntta doing web maintenance from 12/31/20 to 1/11/21. I always kept my toll tag 10.00 and above due to being an Uber driver. I will have a huge issue if I have to pay a zip cash toll when I have a toll tag that's in good standing, and no ability to load it, no customer service available at all today is 1/9/21. I have emailed the mayor of Dallas as well. Do not debit DNT# ending in 1902. If I get a zip cash toll I will take this issue to local media. Your company should have to give every toll tag holder the ability to at least load our toll tags. I did load mine and had a 25 credit on my tag before 12/31/20. This was totally irresponsible for ntta to do business like this. No ability to be able to load a toll tag. Really.
