VOIP Not activated after 14 days

We purchased two Vodacom LTE Broadband packages, complete with Router and VOIP phone.<br> We received our routers on Thursday and Friday 1st and 2nd of October 2015 respectively. The one package was loaded correctly, and the VOIP was active for 3 days, Subsequently, VOIP has been lost, and we have no VOIP capability on either of our two packages now.<br> This issue was raised with Vodacom on 7/10/2015, we have been on the phone with the business support centre every single day since then, being referred from pillar to post, and spent close to 3 hours at Vodaworld repair customer service centre yesterday, however we still have no joy.<br> Our business relies completely on the VOIP service being active, and without it our business is suffering.<br> We are unable to make contact with the \VOIP"team"
