Anyone know why T-Mobile won't resolve Kid Connect problems?

I've used T-Mobile for several years and recently added a second Kid Connect account. Have had problems with this for several months and many times have been unable to reach my children because of these problems. Their solution was to add more minutes to my kids accounts as 'goodwill' (which defeats the whole purpose of Kid Connect, which is to limit minutes). Then the minutes randomly disappear! I have called at least 8 times with no resolution other than telling me to change to a family plan which will cost more. Am ready to leave but don't want to be penalized for breaking contracts. Am totally frustrated and the kids say AT&T is the best.

T-Mobile has admitted Kid Connect has problems and they are no longer offering Kid Connect as an option. Why won't they discontinue this service and give another option for the same price? This has gone on for several months and they still say they are 'working on it'. Have spent many hours on hold or in discussions with reps who have even admitted that it doesn't make sense to add more minutes and that is not resolving the problem. Customer service stinks!
