Unhappy Customer

I was a loyal customer for the past 6 years I paid 3 contract with no default. I recently cancelled my contract with them since the contract ended last month. I called last month to notice them that I won't continue with the contract anymore. Yesterday I learnt that my request was not actioned when I called in, I was told I will have to wait for 30 days again for my contract to be cancelled. I was unhappy with the outcome as I was looking forward to be sav9 every cent that I was paying them. Before the end of the day contract was cancelled yesterday however they forfeited my 20 GB day and 20 GB night. Mind you the data I bought it myself yesterday. I tried to contact Mtn for the resolution I was promised I will be reimburse my data back however it didn't happened. I reached out to their complaint line I was accused that I am a **** I bought 3 GB therefore I should provide proof. As a client I was humiliated by *********** complaint Agent. I felt like I was being punished for terminating the contract. I was told when you migrate from contract to prepaid they forfeit all data you have. To my surprise on my side they decided to take 20GB and left me with 1.9 GB. I asked the agent if you say they forfeit everything why on my account they selected 20 GB and left the 1.9GB the agent and team leader they didn't have an answer for me. Today I called in again I started from prepaid department transferred to contract customer service and transferred to credit department none of this department was of help. I refused to be transferred to be transferred to cancelation department as I saw that all the employees they are incompleted they are even afraid to escalate an issue to their line manager. For 6 years I felt like Mtn was a good company until yesterday I felt like they're ****** who make profit by ****ming customers with unfounded terms and condition that you are being told after they have ****** from you to justify their action.
