My husband made a payment yesterday on his fone yam contract phone.. however, hr was provided an incorrect reference number via sms and the cashier allocated payment to the incorrect reference.... the phone was locked and fone yam refuses to assist my husband and he was advised to.lay a complaint but there response time is 48hrs??? After explaining to them this is not my husband's fault or the cashier at Ackerman as the incorrect reference number was sent by fone yam, they maintained their response time was still applica- bare in mind this fone is needed for work purposes... luckily a gentleman by the name of Zain at Ackermann Westgate mall wen over and above his level to assist and managed to get the device unlocked... to Zain, thank you so so so much for all your help, effort and your appreciated... I will continue to shop at your store as you turned an unpleasant into a very pleasant one!!!!
