Pathetic Service, unavailable tax invoice.

I have logged several calls since November 2021, requesting my November 2021 Tax Invoice.

I call the call center regularly only to be told they are escalating the matter since last year but nobody gets back to me.

I am in urgent need of my invoice, should I seek legal advice regarding the matter or will I be assisted?

I sent several emails to the complaints email address with no success. This is totally unprofessional, pathetic service.

Some of the reference numbers for calls I lodged:

***, 04 Dec 2021 ***, 08 Dec 2021 ***, 11 Dec 2021 ***, 13 Dec 2021

The list goes on and on, but no help.

I am considering leaving mtn and going to social media about the pathetic service.
