Pathetic customer service

I was at Clearwater MTM shop last Friday, app**** for data sim card. Standing there why the person helping me is talking and joking with all his work buddies. After a long time, all was done, and he said it will take 2 hours. Sunday at 9 o clock , I called the shop, then out of the blue an email showed up by them stating all is approved. This will be activated by 12 o clock.. Monday afternoon I called the shop again, explain the manger, he just called the same person.. that helped me.. now the email is missing, he does not know but will check.. Later I received a sms , he resubmitted the application. He called me and said he will follow up and let me know.. today is Friday again.. a week later. The MTN ad reads " come over to the bright side" they should change it to - come over to the dark side with no care or customer service. Even send an email to MTN Complaints, on Monday.. till now response..
