VODACOM BAD SERVICE

I have been complaining for years with the service experience. I have paid my Vodacom account in Full in 2022 and signed a cancellation form but now I am in the red for owing Vodacom, they keep investigating as they say but nothing changes. Vodacom is really playing with our credit score because it has a huge impact now it is difficult to even get a cellphone contract because I am owing something I paid in full. DO BETTER VODACOM EVERYONE IS COMPLAINING ABOUT THE SAME PROBLEM WHEN IT COMES TO YOU.
