lack of feedback

I called on Thursday to upgrade my 2 contacts, a cell line and a data package. Spoke to the agent Samantha who confirmed the upgrade for a Nokia C2 for R99 and Lenovo for R179.I advised Samantha to give me until tomorrow which was Friday last weel to speak to my wife to upgade the package.Samantha promised me that she will call me on Friday to take out the contact.She did not keep to my promise therefore i called on Fridayafter 4pm to upgrage.The agent who i spoke to advisedthat the system was offline and that someone will call me.No one called me the weekend.When i looked at the online deals the Lenovo was now gone to over R200.I am now upset as not of of your 2 agents have gotten back to me to upgrade and now i lost the deal.Iam now thinking of cancelling both contracts as my contracts will be due to be cancelled in a few months.
