!!!!!NO INTERNET CONNECTION!!!!!

I migrated one of my contracts to a RED VIP+ from the 1st of March. Since Sunday, 1st of March I'm struggling to get internet connection and my iPhone only picks up 3G. This was not the case on Saturday. I phoned numerous times and I went to Vodashop in Secunda & JHB. I even did a sim swop. Still the same case. Currently I'm unable to do business for 4 days. I need this issue to be resolved ASAP. This is a huge issue! I tried phoning Customer Care the WHOLE day yesterday and could not get through! Pathetic!
