WORSE SERVICE EVER

I booked my phone in on the 06 February @ Vodacom Tutoit street because it was not charging( LG G3), i receive a messages saying that the phone is with their advance center a few day later i got another one saying i must collect i went there on the 12 Feb, when i got home i released that the phone is still not charging i took it back, i have been going back and forth trying to get my phone back all this day 13,19,26 feb and 06,13,20 March i went to fetch it and found it the same. Vodacom is telling me that the repair center says the phone is working, i am starting to think that they do not even check it they just send it back because they tell me the same thing everytime. the phone was re booked for the 5th time today. i spoke to the supervisor today when i told him i am paying for something that i don't have he told me i am still using the airtime yes i am using it but i am also paying for the device which i don't have and no one is telling me when i will get it back. i hate vodacom right now.
