Zero response and care - poor customer service

I called the customer service center 6 days ago as I wanted to open a new account. I spent 15mins providing the operator with my details and she promised me that I would receive a call back that afternoon or the next day.

After 3 days I called back and was passed around until someone else took my details and promised me that someone would call me back and even confirmed a time (10am the next morning). I set that time aside and received no call. To make things easier I even registered online but received no email or call.

That afternoon I again called the call center and got passed around. I then had the the operator guarantee me that someone would call me back immediately. Again no one called, so I called the operator after 20mins and he said he had asked a lady by the name of Landi who never called me.

Finally I got passed to Yashil Jugga. Who I again spent a good amount of time giving my email address, phone number and even details on my qualification. He confidently gave me his word that he would get a consultant to call me back that day or latest first thing the next morning. (Tuesday 9th April). He even made me take down his name and ref number. A day later still nothing.

To date no one has called me and I have received 0 emails despite furnishing it to several operators and even online. They clearly not looking to acquire any new customers

Surprised and shocked at the lack of service from the frankly useless operators - I hope Investec realizes how many customers they could be losing through the first and most important moment of truth for potential clients (call operators)
