Yet again having issues with Telkom

Yet again i find myself having to log a compliant for Telkom . <br> <br> I recently just returned into the county and i have discovered that Telkom has not delivered what they have promised me again . <br> <br> last month i logged a few complaints and wanted my contract to be cancelled due to various reasons. i got a call from someone in the retentions dept who advised they will offer me a 1 gig a month free for the duration of the 24 months if i kept the contract . i agreed . i was credited with the one gig last month but not this month . <br> <br> i called into the contact centre who said they will be calling me back this still has not happened
