incorrect directions given

Well this has got to be the most unbelievable experience I have had with a service provider. Our contract was up for renewal and we decided to go for an upgrade against my better judgement. We visited the bay side mall branch to do so and we agreed on an upgrade, only to find out 2 weeks later that what we agreed upon is not so. We were on a Telkom mix package and with regard to an upgrade the only option was a S5, when I contacted Telekom today I was informed that we now have 2 accounts. 1 for the S5 and one for Telkom mix. What is going on, this is not the first challenges we experience with being mislead, last year we ended paying thousands and yet nothing has changed. We are still being misdirected an ill informed. This is disgusting.
