Bad service from VOX Telecom

Being a loyal client of Vox more than three years doesnt matter to them. i signed up for a new contract for the Black Friday deals . Vox advised me to cancel the old contract first which i did. They were supposed to collect the wifi equipment on 31 Drcember 2022 and never pitched up. They were supposed to connect me with the nrw account. All relevant documents were sent to them. i sent emails to thiet help desk etc. made phone calls to their help desk. why are no one replying to my emails. as a small business operator im losing out on jobs. i didnt know they are so pathetic. checked with my local social groups and they agreed as well. i want to see if the will respond now. keeping all my contacts and social groups up to date.
