Bad Customer Service and rude employees worse part "MANAGEMENT"

OMG!!! Wow I'm still shook with how we where treated and shouted at MTN Carnival Mall next to Woolworths.

So we went to MTN for an upgrade, unfortunately the pricing was wrong and the content was misleading, and we were told it's not their problem and we are not MTN by Maria and her Manager, it's MTN's problem.

And they did not bother to assist us, instead they both told us to call 135.

I'm wondering if this is how MTN operates these days, customers must make calls for their incompetence and sales?

The only thing they did was to remove the price and told us that they don't even have stock of that particular phone "how convenient."
