Bad service

Good morning, I have been corresponding with MTN Customer Care Division at the main office since 29 August 2021, in an effort to find out : 1. Why I do not receive a monthly invoice ( I go to the MTN branch office at Heiderand Mosselbay to get and pay the invoice , at the office . The service at this office is of a high standard . ) 2. Why my service is suspended each month despite the fact that the invoice obtained at the MTN Heiderand office was paid at the same time , on time . I don't have any outstanding invoice 's and have the receipts to prove same Each time you interact with the Customer Care Division , a different person responds by asking for information that you have forwarded on a number of occasions ( they don't bother look at the file but " pass the ball " back to the customer by requesting information ) -there is no one person that resolves any issue and you cannot make contact with any member of Management as they are always " busy ", but will return your call , which also never happens The service level encountered at the Customer Care Division is of the lowest I have ever experienced and I would like to suggest that the name of the Division be changed to " The Customer Frustration Division "
