Pavilion agent doing *****

I went do upgrade at the pavilion store and I was charged an upgrade fee, which I am told is not on invoice by the call center personal that was helping me. I was told I am now paying for 3 phones when the person at the branch did not tell me that I will pay for 3phones. I want vodacom to deal with person and cancel one phone as it is not my fault that the employees are ********** people who just want to get sales and rob people
