I am very disappointed with the service and bad attitude I gt...I booked my device in on the 7th of December I was asked to make a pay before it will b fixed ...the payment was made and the device returned on the 31st of December wen it came back it was in the same condition I went back their the same day and the told me to keep the device until the Monday and the manager said she will sort it put personally when I came their she **** the problem I've to one of her associates n I left it with him..im in the store everyday n a different associate helps me evrytime when I'm their while shes in her office making comments that I must take the device to Samsung the will fix it for me for free after I paid for a repair that was not done....The service which Telkom garantees a customer is clearly not what I am getting the device is booked in for two weeks again n everyday they still seem to have a different story..I am also using someone's phone n I still have to pay for a device which I dnt have n its data falls away which I can not use I have to buy data and airtime almost everyday for the phone that I am using ..can I please get someone today still to help me get my device before thei
