No communication cost me

Bought a Samsung galaxy s5 with the ADH warranty to my shock I found out that you needed to register the warranty. The lady at the main street, JHB Vodacom branch never told me. My warranty ended on Monday. To register the ADH warranty you can do it manually but you need the invoice of the original device. I tried phoning the branch no answer I tried mailing them no answer. Now my 2 year warranty has lapsed because the branch doesn't correspond with you. Thank you Vodacom main street branch. Thanks to you I lost the warranty and my phone is as good as useless. I was a loyal customer for years but I have had enough. I know you don't care about the little guy but believe me I will spread my word of disdain and even if I convince one person to leave Vodacom I would die a happy man
