Pathetic Service from Vodacom ONCE AGAIN!!!

We have had issues with our wifi connection for the past week or so. Most of the days it does not work, but all of a sudden at night, when no one uses it, miraculously, it works.!!!!! Every time we phone, they manage to fix the problem, only for the issue to resurface a bit later. Both my husband and I work from home and dependent on our wifi. His business has suffered serious delays due to this. I had to revert to my 3G when I can't connect to the wifi - this, also a Vodacom service, is so unstable, that I am not able to continue working using this device! I logged a complaint for Vodacom a couple of weeks ago as well after having to battle for weeks to get another contract cancelled. Only after threatening to cancel all of my business, did I get a Superior contacting me to resolve the matter. This is unacceptable, pathetic and unfair. No problem deducting our money for a service they are not delivering!!! I have had it with Vodacom and their lack of Customer Service and will take this to whatever level and social media platform I need to in order to get this resolved!!!!
