TERRIBLE SERVICE AND NO FEEDBACK

Recently joined RCS Group and I deeply regret it. I was advised of an error on my bank account, so they were unable to deduct premium. I made an EFT payment, sent POP, never received feedback of payment received. Then my account gets suspended after making a payment that was more than my monthly instalment. Then my bank account gets debited for double my monthly instalment, sent emails and have not received feedback. I get an email now after 3 weeks of sending initial query. No apology for the inconvenience, no explanation and my payments are now only being processed. I have never come across such nonsense!!!! The call centre is totally useless, they couldnt tell me why my account was suspended. Telling me it never was, when i ask why i am getting notification of suspension when i check my balance and credit they tell me they dont know it might be a technical error. Then i ask who can help with this 'technical error', they dont know!. how is 'I DON'T KNOW' an answer? after losing my temper I am told I can contact the Technical helpdesk after 19h00 as they are only available then. RIDICULOUS TO SAY THE LEAST!!!
