Telkom Sandton city

Yesterday left my office early to book my modem in for repairs at your sandton city branch, this is for the second time I am taking my contract modem for repairs, I waited minimum 30-44 minutes only to be told that they need a proof of purchase, the last time I booked it in I was not asked for that, and for God's sake this is for the second time I am booking this modem in. the consultant attitude stinks, and he carried on arguing with me while I was explaining to him. I will be going there again this weekend and I want this to be sorted out ASAP. My personal business relies on this modem, I have lost 2 days of no business, with a loss of USD5500.00
