MTN Contract query - No response

I have sent this to customer care 18 times since 3 weeks with no reply. Please see below and then phone me on my number which will be appreciated.

Attached please find all my paperwork regarding my contract. I have been with MTN from 2003 and upgrade each 24 months. In August 2018 I decided to Only take the Converge standard package FF000 as we were having problems of retrenchments at work and I did not want to over extend myself.

I have attached the paperwork they sent me dated 2018 as well as my bill dated December 2018. On my Account profile it does not show the 2018 upgrade it Shows a 2019 which I was not approached about or sent any paperwork, now I am having problems upgrading. How can I upgrade 2018 and 2019 as per my profile. This will be sent to ***** dept.

I would appreciate you to please have a look at my paperwork and come back to me as I have now been in my new employ since 2019 and I would like To take a contract with a mobile phone.

Under no circumstances was anybody in touch with me regarding continuation of this contract after the last papers I received for 2018. And nobody is committing to any of my problems, so as it seems I shall have to take my business elsewhere. All I get from you each time via message on my phone is your query *** has been closed. Please contact call centre i you require more information. Phone them and they know nothing about this or these query numbers. Please your name is going to the dogs!!!!!! Mrs CA Beaver - ***
