False information to close a sale!

I bought 2 phones with free data each month for 12 months. I was assured I could do a sim swop or keep my existing SIM cards as I wanted to retain the mobile no's. After calls and a visit back at the Midland mall branch.... I was advised by Mr Price that it's not their fault the data only works on new numbers. They blamed the Vodacom rep for misinforming them. Great... they were happy to make the sale though. Very disappointing !!!
