Effective August 17, cheques could take 21 days to go through as the micro-lender phases out cheques bearing Rafiki and Chase Bank brands, thus inconveniencing customers who usually enjoyed a two-day clearing process. “Kindly note…Rafiki-Chase Bank co-branded cheques issued may take a maximum of 21 days to clear. We are in the process of issuing you with a new cheque book which will normalise the services,” said Rafiki in an email sent to customers Friday. New cheque books will be available to customers in early September that customers will not be charged for.
