Sick and Tired!!!!!

I do not know who to ask for help anymore!! Why is so hard for Vodacom to put their clients first?? I have been with Vodacom for more than 3 years with my fibre never have i missed a payment!! I did a relocation order a few months ago i was billed R2800 for relocation and R1000 for a new router! I accepted to quote and struggled for a month for anyone to give me feedback! When that was don I requested an fibre upgrade no one told me i am going to pay anything extra! I have paid my R1200.00 every month for my fibre and that 3800 for relocations why am I getting billed for another router? And when I was trying to get a home loan i was advised that Vodacom has blacklisted me for no/late payments! I want to know where? I have never missed a payment with Vodacom why am I being black listed?? I have begged and pleaded for someone to call me and logged calls but no one is getting back to me? How ridiculous is this? How do you blacklist a person for no reason????? I need FEEDBACK!!!!!!!!!!!! And i need someone to phone me who knows what they are doing!
