TELKOM ROUTER ISSUES

Hi guys, please note we are having a problem with our router. the router was taken to Telkom sandton city, and Musa Dlamini gave us a hell of attitude telling us that we cannot book the router in without a proof of purchase, after been in the store for 44minutes last week Thursday . what proof of purchase are they on about, I want you guys to follow up with Sandton store and give me feedback ASAP. that router is going back to the store the second time, this is the second repair.
