Unhappy & frustrated

Good day, I have logged my query complaint reference number *** on the 9th June, on the 11th I send another email as to date no agent has responded to me. The 1st June I upgraded my package to uncapped as I need a faster connection as promised on the package and up this day I have only experience a slow network/connection, this unacceptable as I use this network provider to do my work which pays my salary and this slow paste has caused me not to meet my deadlines. What concerns me even more i just joined Rain last month close to month end I inquired how I could upgraded my package and within a few hours I got a response to my email. The service is not great not sure if I will recommend anyone to the Rain Network, im sorry. my contact no ***. I would appreciate your response please.
