Where is my Data!!!

I have been a customer of FNB connect for 2 years now and I have been quite liniment with the type of service I get from you! From random disconnections to unorthodox network and call quality. Today I have no data on my cell phone to use due to your inexplicable way of doing things! I received 20GB of data when I upgraded from Gold cheque account to Premier, and when I got the R95 deducted from my account I then received 2GB as per my monthly subscription, now to my understanding, I still had 4GB of data from the free package I received and then plus 2 GB of data of my monthly subscription which totaled an amount of 6GB, which then after using 4GB of data assuming it was part of the 20GB quota I was left with 1.95GB of data which makes sense since I am still entitled to my 2GB of data that I paid for!!! Today I was slapped in the face with a surprise of 0.00MB of data left in my connect subscription!!! Now you tell me what the HELL is this sort of service for a client who has been loyal with you for such a long time even through all the garbage service you have been offering over the years?? I am now supposed to make alternative measures to have connectivity whereas I know I have paid to get good service from you?? I don't know how your policies work and I quite frankly don't give a rats ass! I want my 1.95 GB of data left back into my account because I paid for it!! I didn't ask you to upload your stupid 20 GB of data in my account just so you can ***** me over like this! So PLEASE reload my data without further due!
