Bad customer service

I'm not happy about the service I've recieced from Vodacom after being their customer for more 10 years. 4 years ago a consultant from Vodacom called to affer me data contract that was for R75 monthly for 1 GB during and 1 GB at night and was contacte again in November 2017 as I was due for an upgrade of 5 GB during the day and 5 GB for R99. Around July/ August 2019 I can't remember the exact month I called enquire about my next upgrade and the consultant I spoke to advised that upgrade can only be done February 2020. To my suprise in December 2019 I charged R209 of which I noticed deduction in January 2020 and also noticed on my invoice that in January I need to pay R261 and I contacted Vodacom to enquire about this. I spoke to several people where some consultant advised that my contated ended in December 2019 and the amount has changed back into a normal amount as I was paying a discounted amount and other consultant are telling me my contract is going to end o the 22 of February 2020 and they will log an enquire for me with the bilind department. Today I spoke a ver rude guy who could assist me as well where I ened up speaking to his superior Nokuthula who promissed to log an enquire as well with the back officer as according to their system my contract is due to expire on the 22 February 2020. She also gave me contact number for their cancellation department as I requested to my contract as i;m not happy with the service i'm getting from Vodaom. I called the cancellation department they could cancel my contract as thier system shows that I owe R429.62 which is the amount I didnt agree on when I took my contract.

I was then referred to account department where I spoke to Kevin who was a rude and even laughed at when I wanted to speak to his superior. According him, his superior is going to tell me the same thing he was telling me that I was on a discounted contract for 20 months that was ended in September 2019 and when I insisted to speak to his superior he put on hold 4 few minutes and came back tell me that his superior is busy on the phone and will call me before 5 o'clock than he laughed before he put the phone down. I waited for the call from thr sperior and no contacted me.

No one has contacted me from their back but they were just opening and closed logs without a solving to my problem. I want my contract cancelled and my number to be changed back to prepaid. I don't want Vodacom contract anymore.
