**** of network providers

I honestly feel like vodacom should close shop. It's obvious customer service is foreign to them. This is the second time I am writing here to complain. I called almost 2 weeks ago to complain about the amount charged on my invoice I was told I paid late hence the extra R100 charge. This was a lie as I was able show on my bank statement that I paid on the 30th of June 2023. I een emailed my statement as per request. Till this day I am not helped, I called vodacom today and my number is blockedi can't go through. Is this how you help your customers? If you can't solve the problem you bloc them in order to silence them? I also tried to cancel my cellphone comprehensive insurance and I was told the number is not working in return I was provided with an email address which bounced due to the mailbox being full. I am baffled here what am I supposed to do?
