Bad service, impatience and bad advice

I was assisted by a guy named Thabo Nkoane, he was impatient. When i asked him to explain to me, he muted my call until I hung up. I called to ask to reduce my loan repayment for the next 2 months. He instead advised me on something else, when i asked for 2 months and a specific amount, he gave me a higher a mount for 1 month and then changed the next few month to something else. When i called back, I got exactly what I asked for. I asked Thabo a few times what he meant by 1 month, he instead muted me until I hung up.
