Telkom: clear, transparent, excellent communication, well priced- try somewhere else

I have been with Telkom since January 2019. A loyal paying customer. They contacted me 2 months ago to ask if I wanted to upgrade to a 25mps for no additional charge. Nothing is for free so I queried this a number of times and was assured this is the case. I believe because this speed is now standard. Of course the next month I was directed debited double the amount. I sent an email of complaint. The response I received 2 weeks ago was a blank email. Sums it all up. Well done for your clear communication. In addition my internet slowed down when it should have sped up. Throttled much? Farewell Telkom.
