Complaint still hanging

I have published my disappointments with Cell C on the 3/06/2023, of which my dispute was not handled within my level of satisfaction. I rep**** on their responses that i need the matter resolved and to date, nobody has called me to tell me about the way forward. So i'm on my best of pits with Cell C's service and i did not get all the items that were listed on the sales call. So now, what must i do if i keep on receiving sms's that my payment is overdue if they are the ones that did not debit in the first place! WHAT IS PRO RATA AND JUST CHECK CAREFULLY ON YOUR RECORDS IF THIS WAS ADVISED TO ME.OR MY DAD, THE SERVICE IS HONESTLY HORRIBLE. GEEZ😑
