Terrible service

My name is Lindokuhle, I am a client of Capitec Bank for about 4 years or more now. I have a problem on the 24-07-2020 I went to Capitec Boksburg branch to increase my Facility access account Limit and the consultant who assisted me switched my account to a Long term loan of 56 months without telling, the next thing I found myself paying R2000 for interest rates and only R200 of repaying the loan. I went to Dawn Park branch to switch back to access facility account so I can repay the loan and reduce the high interest rate and Capitec bank rejected my application. I have tried to reduce the months of repaying the loan and I am now paying high instalment. My credit record has been ruined. Why should I suffer capitec stuff that is incompetence, and apparently I was not the only client to experience that. For what is worse it’s costing me lot of money and that is totally bad because I switched to capitec to reduce bank charges and interest. My credit record is now bad because of someone’s mistake, I wanted to apply for a car finance now I can’t because of this loan. I need help from capitec I can’t be paying for someone’s ignorance and mistake. Something must be done and must be done soon because I need to apply for a care. This is my first to apply for a credit at capitec and it’s the worst experience. Please help me I am under a stressful situation here.
