Customer service attitude

I lay bye a mobicel notebook from Umzimkhulu Ackermans in De Bryun plaza yesterday 21 October 2020 for my daughter she decided she does not like the brand so this morning I went to ask for my refund the consultant says I should wait until January to get my refund which is the end of the lay bye term, I asked her to read the terms on the deposit slip which term 4 states that the deposit will be refunded by Ackermans immediately should the customer decide to cancel. I would suggest that Ackermans looks into customer service in nmz and train their staff to know how to handle customers without attitude
