MWEB Talk number porting is disaster

Hi, as Neotel stopping cdme and other wireless services needed to move my business landline to Mweb Voip service, so recently regisetered with MWEB talk and ported my neotel number to mweb, number was ported on 07-05-2019 around 12:30 pm, immediately the mweb talk was setup using zoiper application, but the ported number is not working, so far spent 200 minutes over the phone and they keep telling it was sent to technical team and there is no response, the number ported was for an Indian restaurant and most of the business runs on the number, lost around 30% of revenue for past 3 days, i begged and cried to escalte and still get the same answer that they will respond when the tehnical team responds, it is frustating and made a huge mistake to go for mweb talk, based on responses from mweb look likes there will be nothing done untill next week, this is huge business impact, not sure where to go so approaching hellopeter for help. Thank you
