Spark Account ******** me from Annual Discount

In December 2021 I paid an amount of R28,100 covering the outstanding amount for 2021 fees and the annual amount for 2022. I received no acknowledgement of the payment and I logged an enquiry of the Spark website on 13/01/22 and received no feedback. I called the accounts department and spoke to a rude agent by the name of Sihle on 27/01/2022 to enquire what was happening as I received no communication regarding my payments. He insisted that I should check my statements, I confirmed that I am not receiving my statements and demanded that he log a query with their IT department to investigate why.

Fast forward I started receiving statement after a couple of months and noticed something was amiss, then I called on 07/12/2023 as I noticed that the discount for the 2022 fees was not app****. I spoke to Nelisiwe Lukhele who confirmed that she doesn’t have the authority to assist with my query and my query would be passed to Tashni. Nelisiwe emailed Tashni and copied me in, no acknowledgement nor a response was received from Tashni, I followed up with another email on 20/01/2023 and still have not received any feedback.

Spark Accounts is ******** me out or R2500 when I settled the 2022, please can I get some assistance.
