POOR CLIENT SERVICE + LIES

i have problems with my samsung A3 phone, re been slow & screen flickering. i called the service centre at nandi drive they said i can bring in early and they will have done by close of day. when i left they were already busy with the backup and they said they will call when complete. at 3.35pm i called and asked to speak to shane who was busy with the phone. i left a message and said was urgent. at 4.02pm i had not received any call back. i then phoned and spoke to shane. he said he tried SEVERAL times to call around 3pm. i have no log on my loan phone re him calling and no msg was left. he said he he was unable to work on phone as had a vodacom protect password and that i must get from vodacom. i require the phone for business tomorrow and i am leaving DBN for a few days on business. i i then spoke to kavish the owner of the call centre and explained my dissatisfaction and that he must check call logs and give me a reply on how we can sort and go forward. he was also not that helpful and said that they close at 5. i then chatted to ashley the KZN manager, but no luck. he refused to give me his managers tel # and said i must go via call centre. i do not see them go that extra mile
