Stinking service from Telkom,renewed contract on 20.04.2019,received Samsung A50,after 2 weeks couldn't switch it off took it back and for replacement, consultant from Telkom Greenstone booked for repairs instead,came back on the 25/5/2019 I was told that software was upgraded, today,same phone is off,called Telkom centre ,promised that Manager from Call centre by the name of Charmaine Ma***u will call me before 61.30 today,I asked my husband to take handset to Telkom Greenstone mall,which he called me while he was there and consultants was so rude to me over the phone,Telkom service is so bad,Consultants and Managers are so unprofessional,I am still shocked,no is bothering to call me and give me way forward as a client!!!
