Incredible poor service

Dear Reader,

Upgraded couple of weeks ago from 10MBPS to 20MBPS. Although my invoice reflect that it is done looking on www.telkom.co.za it is clear that it has not been done. Have made numerous calls to general inquiries, sales, billing and technical support without any joy. Also did the sms "service" but no feedback. Did get 1 call from Telkom to hear if I am happy. I mentioned problems and again got send to tech support but lady seemed not knowledgeable on how to assist. Tech support promised a reference number via sms which i also did not receive. How on earth can such a simply query be such a huge challenge to Telkom? It is also becoming extremely frustrating trying to get through. Constant message of high call volumes and you might have to wait a long time is order of the day. Pls help

Kind regards Cees Meiboom ***
