Displeased by Telkom service

I'm very much disappointed with the service that I am receiving from Telkom. I took a contract with Telkom on their 2018 black Friday deals. The package came with a Huawei Mate 20 Lite on FreeMe 1GB – R399 x 24 plus a free 120GB which is loaded 5GB x 24 Months. However I have to date not received my free monthly 5GB data whis was the main reason I took the contract.

I lodged a query via Telkom's customer care line, where the consultant I spoke with opened a case for me with a reference number, this was on the 6th August 2019. The consultant told me that Telkom takes 72 hours for the case to be resolved. After the 72 hours had elapsed I then called again the customer care line to find out the progress on my case. The consultant I spoke to told me my case has not been assigned to anyone and I need to wait until someone from Telkom calls me. I then asked to speak with a manager as the consultant failed to give me the exact time frame that I should expect the solution. I was then transferred to Mr Clifford Mohale who promised that my case will be resolved in 24 hours as it has taken longer than the required time. Still no one from Telkom called me regarding my case and so after waiting a few days, I called the customer care line again. Upon expressing my query with the case to the consultant and I was advised to continue to wait for someone from Telkom to contact me as my case was still not yet assigned to anyone. I was very displeased and asked to speak with a manager. The person I was transferred to this time was Mr Levi Mohale, Levi gave me his email address and said I must email him my query and he will direct it straight to the supervisor of the department that deals with cases and they shall indeed resolve the case and call me back. After speaking with Mr Levi Mohale, I sent that email and also decided to drive to Brooklyn Centre to the Telkom sales branch where I took the contract. The salesman who assisted me there was Mr Kgopolang Mahlangu, who decided to open another case for this same query and gave me a second refference number, and said it shall be resolved. I waited again for a few days and still my query was not resolved so I called again the customer care line. The consultant I spoke to this time told me my case is under special investigation and so I must wait and call again after a week. I called again today and the consultant I spoke to told me the same excuse that my case is under special investigation. For a total of 21 days I have been back and forth with Telkom without any resolution to my case.

What I need Telkom to do is to reimburse me all the data that is due to me i.e. from November 2018 to date.
