NO SERVICE WHAT SO EVER

I have been trying since Saturday morning to sort out my phone with Vodacom. As my phone was ****** a week ago I had to do a sim swap and now I am struggling to use my BIS. I can browse on the internet but now all is coming off my airtime and I have BIS Active on my account. Spoke to a guy on Saturday, he was to phone me back and never did... Went to Vodacom shop in Westgate, they could not help. Went to Vodacom shop in Campus Square this morning, lady who did assist tried everything she could but could not get everything right and told me to phone 155 number. Done that but was diconnected, phoned again, was hol**** for 55 minutes before being \assisted\" by Lebo Masia. Again did all she asked me to do, said she would phone me back in 15 minutes. That was more than an hour ago. I get no service from Vodacom and although I supposedly have BIS activated on my phone I am being charged for everything. Why if I have BIS activated on my contract and paying it every month. I need this problem solved immediately and a credit to be done for all airtime that was lost since Saturday. "
