Bad bad very bad services when you walk in a Vodacom store the hole freakin starve surround you to make a sale but when you have a problem they all stand far away from you I bought a Samsung galaxy A12 within 6days I saw the phone's faulty phone heats like a pressure cooker phone came back after I took it in and was classified as OBF it came back and the same problem still persisted it heats up while just using WhatsApp which is very unusual for a new phone and now they had send my phone back again like what the actual hell I love the phone I don't want my money back just a different phone as mine is defective it's been 2 weeks since I purchased the phone and I only had the phone for 6 days I bought the phone because I needed a new one now I'm completely without anything but a paid R3000 for it why do I get a broken phone I didn't give Vodacom broken money so why a broken phone I'm filing a case against Vodacom and there ****my tactics I really trusted Vodacom as I bought all my phone's there without any problems now why start now Vodacom is going in downward spiral you'll hear from me in court soon....
