Upgrade contract was changed

My vodacom contract was supposed to be ended on the 31/07/2017 and i decided to extend the contract for another 24 months which i phoned the call centre and spoke to Phumeza to let them know that i am changing my contract to a new one so that i can get a devise because initially when i phone the first time i asked that my contract should only be the one that you only receive airtime,and when i phoned again on the 15/08/17 i spoke to Siyabonga Madida who i mentioned to him that before the end of july i spoke to a consultant who refuse me to change my contract back so that i can get the new device & i was very angry when it was said that i cannot change but Siyabonga Madida gave me an excellent service & advising me on which what he can offer so that i can get a new device,i was so shocked to hear that it can actually changed without any problems & i was so happy because Siyabonga gave an excellent service he has exceeded my expectation experience by giving me a prompt & effective response of my issues,Siyabonga's service is outstanding . i have received my new device and my contract was changed to what i wanted and i am happy with Vodacom my reference with vodacom(1- ********** ********** ) Thank you Siyabonga Madida Great customer service
