Dissatified with quality of Internet

While I am a staunch supporter of Telkom -- have 2 cellphones with 8ta and shares in the Company -- I am at odds with their Internet service delivery. I have a Do2 Broadband (under 24 month contract) with them, which should deliver a 512MB down- and 1024MB upload. Regrettably at times it is almost non-existent. Tuesday evening, 17 February, I attempted to download a program from a website and instead of a download speed of 512MBps the speed varied from 6kbps to 8kbps and 10kbps with at times zero. Notwithstanding, that not only I had logged a complaint and received a reference number -- 2019CRK090215 -- therefore, but also that on complaint that the problem had not yet been resolved I received an sms, on Wednesday 18 February, that the matter has been escalated, nothing appears to have transpired and I have had no further feedback from them, which leaves me at a loss, and with now but to ask: Whereto Gehazi?
