Poor service

As A loyal customers of Telkom that pays his account every month is the service delivery very very poor.I have experienced signal problems with the internet my wifi over a few months.I just contacted customer service about my problem we're I was informed to upgrade because the product that I'm currently using is no longer available.My wife currently started a small business from home and she is dependent on the internet wish is one of the reasons am so an happy I was shock to hear that there is no references nr for my call about the query that I have locked.I have not been informed by any salesperson to upgrade to a new product but each onth am paying for a faulty internet line
