Stay away from Telkom

I took a Telkom mobile data contract out in March 2017 and apart from a usage problem in December 2017 that remained unsolved all went well. Suddenly at the end of March 2018, throughout April until now I had no data. Despite hours on the phone with 2 case numbers ( ********** 1 and ********** 0) and four visits to the Mokopane Telkom shop my problem has not been resolved and I still don't have data. I have requested that my contract be cancelled and I be refunded for April 2018 and I was told that someone will phone me. That was on 2 May 2018 but to date nothing.
