17 year customer and very unsatisfied with customer service received today 4/9/2025

I called T-Mobile today because last month I called on 3/8/2025 to disconnect my watch service and today I still had charges for both watches on my bill.  I called and agent told me that they did not disconnect my service.  It was only suspended.   She also told me if I disconnected the lines I would not qualify for promotions for the next three months.  I was a little upset because I've been a customer for so long and was just asking for two watch lines $24 to be disconnected and now, you're telling a 17-year customer that they don't qualify for any promotions for 3 months.  I was so upset.  She stated there was nothing she could do about it.   I decided to call back and speak to someone else. 

This time after 20 minutes on the phone at work customer service person tells me I am not able to get a credit I can only get $10 off bill.  I explained I should be credited because I called last month or at least a little more than $10 since bill cycle starts on the 6th and I called on the 8th.  I then requested a manager.  She then comes back on the phone after 5 minutes and says I need the primary person on the line.  I tried to explain I had account permission.  I was never told till today by the fourth person I talked to that I as an authorized user had no permission to cancel or add lines - never had a problem or told this before.  Cancelled other things but today after 17 years it was a problem.  I hang up the phone with this customer service person now more upset.

This time after being extremely frustrated I speak with customer service rep Diamond who is able to assist me with canceling lines and gives me a credit for the charges.  She explains I can't cancel lines or add lines even though I have account permission which I'm glad she explained but after 17 years I am told this.

I am glad Diamond was able to finally cancel the lines and credit my bill.  Thank you, Diamond, for your service today.  But I am highly dissatisfied with the other calls I made today.  I never had this experience with T-Mobile.   4 calls later, 20-minute call at work and missed half my lunch break to get this solved!!!!!!!!!!!!!!!!
