Vox disgusting service again and again and again!

me again. still fighting with Vox. they finally did my installation after endless fighting. now they've sent me crazy invoices that i don't understand. i asked them to call me to explain, but obviously got no response. that's from tumi my client relationship manager. i also also asked her for some information to install some new handsets. still waiting a week later. it gets worse. remember those penalties they wanted to charge me? well we did agree to a reduction because they moved with me, and let's not forget why i had to sell my premises and move - like hello, my father and business partner died our CEO died! and my mother, our general manager landed up in hospital for 5 months both from Covid! leaving me and my 3 remaining staff members to manage an entire business on our own! nice and sensitive company Vox are! well they sent me an invoice for the penalties also for R94 000 odd! jaco the guy (who is meant to be some sort of manager) organized the reduction (took about 6 weeks). well he just doesn't answer calls nor reply to emails. maybe he's left Vox, but no-one told me. i just can't get the guy to reply! the thing is, they have these amounts on their system saying we owe them! imagine how this can affect our credit rating going forward. and just no-one reacts. tell me, other SME owners, how are we meant to function as businesses in an environment where your most critical service provider, just isn't interested in providing a descent service? maybe they can't! every other service provider we use, gives a 24-48 hour MAX turnaround time. without numerous calls and emails and fights. vox just doesn't! i WISH i could leave them!
