An unactivated Vodacom SIM with Mweb

I bought a wifi modem from Mweb, and it was delivered in Aug. I have been trying unsuccessfully for a month now to get Mweb to activate the SIM. Nobody is taking responsibility. Mweb blames Vodacom who at this stage cannot answer for themselves as my account is with Mweb. Its the 2nd month now that I have paid for said services without the pleasure of using it. I run a small business from home and as of last month everything has come to a standstill. It has left a really bitter taste in my mouth. Up until recently I considered Mweb forefront in our country when it comes to customer service, sadly after this experience not anymore. They are passing the buck to activation, back office, sales, anything but resolving the complaint. Please resolve my complaint. My reference number is MWB **********
