Waiting for over 2 weeks for statements !!!

I logged a ticket with MTN via their call centre (135) to obtain itemised billing statements , on the 08 January 2020. I was informed it would take 2 - 5 working days to resolve. i followed up on the 14 November, and was told the matter was escalated to the 'back office dept' . I followed up again on the 17 November and was told again the matter was escalated. 22 November, still no statements, I called in again and requested to speak to a CC manager. I then spoke to a 'Ndumiso' who promised the matter would be resolved within 24 hours. Lo and behold, 24 hours later, 23 November, i called 135 again and spoke to 'Ndumiso' who again promised he'd call me before his shift ended at 17:15 to give me an update. I am now waiting for over 2 weeks for these statements to be emailed to me - this is the most pathetic service i have ever received.
