No hope for Vodacom anymore, i have lost faith

I have been trying to contact Vodacom collections for the month of April but as usual they don't respond or the phone just rings, not even the customer care consultant can get through to them. They have debited my account with R2 600.00 and i don't know why, so obviously i didn't pay. i have sent 8 emails to Vodacom no one have responded, really what did i expect. this is a clear indication that i need to move to another service provider. I gave them a chance and they messed up again, this has been going on since Oct 2021. I just need to know why they have debited my account ???? Then they will put my name on ITC without contacting me, is that fair !!!!!! i really have lost faith in Vodacom now, i have had it, from now i will be looking for another service provider, that's it !!!!!!
