Vodacom Refuses to provide statement of contract

Vodacom has failed to send me my statements of my cellphone contract in order to view the amount of money I have been paying them since 2020 up till now, I believe they have been ****ming me and taking advantage and tricking me to call their pre legal department knowingly that they wouldn’t be of assistance as my case go nowhere. I find it extremely frustrating that I have to pay a contract for more than 3 years without any proof of account statements and to make it worse they have deleted my phone number and in hopes of blacklisting me after paying for my contract for many years now !!! I could be paying much more than I was paying but they’re not giving me my legal right to get my information. They’re not good for business I have been sent back and forth and I am tired of them wasting my time I’d like to expose them for their *****
