I resent, MTS - kidalovo

Today I discovered that the tariffs of “RED” and “We” suddenly became not by the second, but by the minute.
For those to whom it doesn’t say anything, I’ll explain that the RED tariff used to be:

• Subscription fee 0
• Per second billing from the 1st second
• Price 1 minute 5 rubles

I chose this tariff because I’m calling a little and the calls are usually short, as a result, the expenses are about 100 rubles per month, my wife has the “We” rate, everything is the same there, and she also spent 100 rubles per month.
And now, suddenly, the costs per month were 600 rubles per person, I think you understand that this is just a huge difference.
We looked at the details of the bills, after which we went to look at the tariffs, and we see that our tariffs have become per-minute, and the price has not changed in 1 minute.
Well, judge for yourself what kind of brutal fare - 5 rubles per minute, per-minute billing.

I'm just in shock. And what can you do here? I don’t want to sue them, I don’t want to call them, I just change the tariff or operator.
Minus MTS Karma here in Habré, and now I decided to write, let people know.
So if you have an MTS, check if your tariff has changed (I checked only my own).
