vodacom staff poor service

Dear sir<br> I have been a customer for the past 10 years from a pre paid to a contract it is shocking how store managers are been put in place to run your business. I have had a problem with my hand set as I had to renew my contract so on the 5/07/2015 I have walked in your vodacom g.way store and have been told by your sales guy the S6 edge is one of your better fones. I have asked him bout battery life and soft ware problems and his words is that it is a better form an there is no need for any other fone he also stated that if the fone give me any trouble I must bring it in store and he will swop it. I have a problem with this device and found that the battery is going down all the time. On the 12 /07/2015 I have walked in store as I am very busy during the week day and can't make it out of the office. I have approached him and he said I must take my concerns to vodacom and Samsung direct. <br> Shocking service plus I have had a witness on my side.<br> I just want them to take this handset back and cancel my contract I am well within my rights as a consumer
