unfulfilled promises

I have requested a copy of my vodacom contract on the 5/1/2016 as my Samsung s6 edge plus was damaged and Samsung requires proof of purchase in order to repair. I was told that the process would take no more than 10 working days. It in now in excess of 2 months and despite being promised action via sms from Lulama Sibisi and Bruce Bester, and countless calls to Vodacom I have received nothing. The staff at customer are extremely unhelpful and only too happy to transfer customers to yet another incorrect department. Nobody takes ownership and supervisors are conveniently unavailable when you ask to speak to one. I expected more from vodacom and this is not an isolated incident as I have called several times and each time I experienced the same level of indifference. Truly disappointing. ..
