Misleading and False Claims to Make the Sale - I have lost my Trust in Vodacom

I was contacted over the phone to take out a LTE modem 5GIG for R200p/m. I asked several times if this contract will replace my existing contact and is not an additional contract, if I can also use the sim in my phone and my number would remain the same, to which the response was yes yes and yes. When I received my LTE modem when putting the sim in my phone no one could contact me (only to find out that the number on the sim is another number). I phoned the call centre to find out that this contract did not replace my contract as promised but was an additional contract, which now has financial implications for me. When I phoned the call centre to let them know that this contract was sold under false information they told me that it would be investigated and someone would phone me back in three days time, I phoned back because no one was phoning me back they said that no call was logged on the system for any investigation. Very dissapointed being **** to - this may be how you 'get' your sales but not how you maintain your sales Vodacom :-(
