Wefix's useless repair centre

I took my phone to your Canal Walk store on Fri 14 June for repair under warranty. 4 days later I had not heard a word from you. I later discovered that a) you decided you didn't have my POP (which I supp**** in November when the motherboard was also replaced and you had my phone for ELEVEN days) b) that you therefore decided to create a quote for me and c) that you sent it to a lady in the Netherlands since you captured my email address incorrectly d) she responded twice this week and also in December that you had the wrong address, but you didn't try to phone me instead to get the correct details. I finally get hold of a manager, Adnaan on Tuesday who assures me that he will look into this matter, find out when he can get the part and would get back to me ASAP. By Thursday I had still had no feedback from him on the ETA. You answer my mails with "we are awaiting parts" - useless info - I need to know WHEN you are expecting the parts. I finally go to your shop again and ask for Adnaan - he has gone on leave (amazing how that always happens when you look for the same person again...). I ask to get my phone back since you clearly don't know when you can fix it since you apparently have no idea whether the part is coming from Korea of JHB or goodness knows where else. How is this possible?! Do your computers not work like other computers in this century? Samsung, since you have partnered with this repair shop and I have had to wait for my phone TWICE in 6 months, be assured that this Samsung Galaxy will be the last I purchase from you after being a loyal customer for 10 years and bought 6 Samsung phones.
