Exremely Pathetic Service

I struggle a week now to change my number on one of my contracts due to constant ransom messages on whatsUp. I don't have any use of my account and mtn is absent. On Friday when I went to the Irene Village Mall to enquire why the number change was still not done, Vannessa confirms that the department working with that requests were not working, yesterday I went to Vannessa again and apparently that department did not work yesterday too. I seems that mtn is in total lockdown but the debit orders are still collected.
