Telkom: Terrible Service and Poor connectivity!!

*** On 21/08/2019 I phoned Telkom to upgrade my internet speed and we decided on the 20mg speed line. They assured me that it would take place within 3-5 working days. Today 28/08/2019 I phoned in to check on my status and they told me that they do not have the speed line available in my area. They told me to change it to the 10mg speed line. I am so annoyed because I have online business to take care of and I only got extension for tomorrow 29/08/2019. My children are students that are also in desperate need of a good internet connection. I am constantly having problems with the connection and their terrible service. I am so annoyed with Telkom and its poor service!!!
