Package Trouble & Not receiving full benefits (Theft)

I have been a Cell C customer for so many years now and I'm so disappointed and disgusted by their treatment towards me. I took out an LTE Pocket router contract in 2017 and the benefits are 10GB Day-time & 10GB Night-time data package for R199. Last month I tried to use my night-time data and it wouldn't connect, when I checked the balance it showed that I don't have data. I called them on 23rd May 2019 to lodge a complaint and the person that was assisting me said that the turn around time for the a response is 48 hours and further confirmed that the 10GB night-time data does not reflect only the day-time data reflects meaning it was never loaded. The 48 hours lapsed and I called in again on the 28th May 2019 to make a follow up only to be told that the complaint that was lodged on the 23rd states that insufficient information was provided and that I will have to lay another complaint. I did lay another complaint and the lady that was assisting me also confirmed that the 10GB night-time data was not loaded for the month of May, the lady also told me that the turn around time for response from Cell C is 48 Hours! I had to call in again on 4th June 2019 to make another follow up and now I was told that I am on a 5GB package instead of 10GB as reflected on the statement of the month of April 2019 and I did not get the night-time data again for the month of June. So in a nut shell I have been paying Cell C their full premiums and have never defaulted on any payments due to them for the years that I have been with them, but today I find myself cheated out of the benefits that are due to me. I am dealing with a case of not receiving my full benefits and I don't even know how far back I have not been receiving them, the one minute I'm on a 10GB package and the next I am on a 5GB package, to top it off they continue to not load my full benefits again for this month after laying a complaint last month. I have never given Cell C any trouble, I have been a loyal client for so many years and this is the nonsense that I have to deal with and they don't even have the decency to CALL ME back and make a follow up. I regret entering into another contract with them, I just didn't know that I'm dealing with ******* and **********.
