Tello review: There is no customer service, you're on your own!

I have been using Tello service for a little over a year now and it was stellar until recently when they had a problem with the payment. I had a payment card that had a few dollars left on it and another full card attached to my account but their system can only process one card per month apparently, it just comes up as payment denied. I chatted with customer service to find this out so I removed the partial card. The incident caused their system to reject the full card then and my account was suspended leaving me with no phone/internet to diagnose the problem.
It took me 4 days to get into town, get another card and use a friends internet to find this problem and then load a new card to my account and reactivate it after trying to get the other card payment to go thru to no avail. I got a message that gift cards could be a problem, despite using them for over a year, and so I should load my bank card instead defeating the reason I signed up for the service in the first place. On top of that, the service did not change my renewal date to account for the 4 days I was without service and so I am also losing that time. Real pain in the arse.
To be fair, up til then the service is a real value in this writer's opinion. Would be good for them to address these kind of problems with actual customer service or other fixes
Would like to see the 10 gb hot spot/tethering limit go away, doesn't make any sense and would like to see a plan that has more than 50 gb data would be nice.
