Pathetic Service

I am loyal customer, it been years banking with Capitec , i have been disappointed with their services and they process, I have a loan account and am about to close it as I am left with 3 month to finalized it, since I had the loan account the debit order has been going through smooth without any issues, before my salary reflect on my account , loan account is the first to be debited and follow the rest of my debit orders, this month suddenly it did not go through as usually I did not notice as other debit were notifying me, after I week I received a SMS stating my debit did not go through without a reason and the message apologies for this unfortunate, Capitec agents has been calling and when I answer they drop, I have not spoken to a agent to explain what was the reason for the debit order did not go through, now am receiving sms to pay and everyday the interest increase , who was at fault in this case and why from Capitec the debit did not go through and why am the one I been penalise, this is deliberately from Capitec as I have few month to close the account , worse service ever when I requested my credit card limit to be increase , was told I don't qualify but I qualify for a loan amount 140 000 , day time Robert , the app service is pathetic, what a waste of my time with this bank , any am busy shopping around hopefully African Bank has better service....
