Got the following email from T-Mobile for my T-Mobile Home Internet payment.
Oh no! Your payment didn't go through
We weren't able to process your recurring electronic payment from your account XXXX. Because of the failed payment, you have been un‑enrolled from AutoPay. Please make a one‑time payment today at t‑mo.co/pay and update AutoPay settings to avoid late fees and suspension and keep your AutoPay discount, if applicable.
Your T-Mobile Team
Last month the payment was processed using the same card (without an issue) and there are ample funds in the account (the account is a debt card account).
I logged into my account selected the payment option and the payment processed immediately.
Even though I like T-Mobile issues like this make me very wary of their service.
