Good onboarding, but poor follow-through and lack of support at all

Bad service, communication and dishonesty. When you first in communication you would think that these people are good When I started and was onboarding, they used to call me every hour by Shipho but when is time for support, no one is there. I logged a query on March to say I would update my accounts as there was money I paid directly to my creditors, they requested statement from the bank, the bank responded 10 April to this day my account has not been updated ,I was told Sesethu will call me last week of Friday before 11am , Till today I have not received a call from her. I logged another inquiry about the bank charging interest of 21% while they said the bank agreed with 0.11 % but no one has responded as well. The worst decision of my life.
