Billing and update payment method

I tried to change the payment method and his site did not allow it to me, however, they charged me a transaction of $ 20 and another of $ 69.00, they have me with blocking in the service, they have not solved the $ 22.00 of credit in my favor, at to place FreedomPop Safety Mode, I was charged on 04/14/19 at 3:15 a credit refill with transaction number 131115365, when 12/04/19 at 10:59 with transaction number 130970632 I paid for the FreedomPop Safety Mode, When I called on the phone they explained that the $ 2.00 pending and the additional $ 20.00 could not be reversed, that they accumulated for the annual service payment, since Saturday I am waiting for an answer, the day now to see that the service was blocked, I change The payment method, however, when placing save does not, but if you made the discharges of my credit card, I expect a prompt response, what bad service they have in their support and collection system.

The day I tried to change the payment method, and they charged me $ 20.00 without a concept and tried to charge an additional $ 69.00, with a credit in my favor pending $ 22.00 that their support escalated to their superior without giving an answer, I wait for an answer, because $ 67.76 minus $ 22.00 is $ 45.76, and they are charging me $ 22.00 plus $ 20.00 plus $ 69.00 in total $ 111.00, please resolve this situation

When making the initial purchase of the service they offered me a promotion that for an additional $ 0.01 could take an additional line, I finished the purchase process and when I received the package by mail only a SIM CARD arrived, I speak by phone to the support call center and I did not I understood the operator since he was from INDIA, and he did not speak English very well, to date I do not understand why, but I do understand that this promotion was not fulfilled, since they moved away that the transaction had failed, however, when one dispute so that they integrate the money assure that it is as credit in favor and the money will not be lost.
