Hopeless Telkom

So I ordered the Samsung Galaxy S9 online and I need a typed out proof of purchase. So I contacted the Sales department on 10213 and the consultant told me she's emailing me a proof of purchase but surprise surprise she didn't. So I contact the Sales department again just for that consultant to tell me to contact the Billing department on 10210 which I did. When I eventually get through to the Billing department they tell me to contact the Sales department. This is beyond frustrating as all I want is a damn typed out proof of purchase. I'm not asking for the moon and stars.
