Very bad customer service with no accountability

rude supervisors and rude customer agents who keep sending from pillar to post after I was incorrectly billed over half a million for a product that’s not even that worth. A billing error they keep sending me from pillar to post for. No one in the of MTN South Africa knows what’s happening. Rude agents who keep speaking over me. No apology and no patient. No acknowledgment for my frustration. No one can send me an invoice and no one wants to confirm what they keep telling me over the phone via email. ZINHLE the *********** TL gave the phone to an agent as I was speaking to her . She entrusted a who agent who failed to resolve my query to come fail me again. Now my calls are not even sent to survey for rating. The reference I got yesterday from their official page cannot be tracked by their agent in csc. Instore they waiting for csc and csc is sending me back to the store. No one is taking accountability. This is an contract less than 2 weeks old and I was told I won’t be debited this month but now their story changes to I’ll be billed on the 30th and no one can say for sure how much except the ridiculous amount they see in their side that’s over **** with a product of under 30k. Over 10 calls to you guys since yesterday and none of them yielded positive results. No reassurance that it will be resolved and that it is an error, no accountability except that ***** was committed on my account the next thing it is not ***** then I’m told they don’t know anything . You paying games with me as a new client and my experience with you guys is already sour. Take your csc agents for training as no one explained to me what the issue is and how your products work and how it will be resolved. Take them all for training including Zinhle the CSC TL
