MTN and mondo if off the grid, zero connection is what you want

After the most ********** service, being ********ly suspended and over a MONTH of continual calls , emails, hours upon hours of holding, I was finally told that the matter was resolved and mondo would credit the mistaken charge. This morning I awake once again to a notification that all 3 my lines can not make calls because of an outstanding amount that I do not owe. Tomorrow I’m traveling and will be reliant on GPS etc, that I will not have access to. I will also not be able to conduct any business!! How long before I hear the false promises of resolve again?!
