Letaba Networks is the worst

Letaba Networks is the worst service I have received in a very long time with calls that just keep on reading the same message over and over called them more than 20 times and the calls automatically drop themself at 30 min holding on the accounts department reply on emails stating you need to go on WhatsApp and activate the account but the WhatsApp line is not even working we had to move training sessions that cost our production heavily and still to this moment no replay 15 emails later they just don't care what happen technical department said they will escalate the matter but no luck took my details and everything
