Worst service provider!

I have a fibre line with Vodacom. I don't get monthly account statements and I don't even get debited on the correct date. I'm not sure who authorized the different days on which they debit my account. Their call center consultants are never sure of anything and it's never their fault. 1 consultant even told me that my issue is Vodacom's fault and not hers. I mean, doesn't she represent Vodacom? I once worked for Vodacom and had no issues with anything cellphone or fibre related. But since now I'm an external customer, it's problem after problem! I'm disgusted!
