Telkom cresta, worst manager and service ever

Good day, today I'm one very disappointed customer..... we have a 10 mgb fiber and a zyxel router we took the contract out @ the telkom cresta store, on the 25th of april 2017, for a while our internet keeps on connecting and disconnecting, so i phoned to configure the line, and they asked me to press the off button and switch it on, so then the on button does not stick so it does not work, they said to me please go to the store they need to give you a new router because it is still under warranty until the 25th of april this year, long story short i went to CRESTA TELKOM and i have a 2 month old baby... so i waited about 20 min to be helped by the technical department, they told me sorry there is nothing they can do because it is a hardware problem and even if they book it in to the repairs in kempton park they will send it back because they dont fix hardware so i need to buy a new router EVEN THOUGH IT IS STILL UNDER WARRANTY, so they send me home after a 2 hour fight with my router fixed with sellotape, i told them the software is also faulty the said no nothing is faulty on the router so i came back home phoned again to configure the line, and still it did not work so the consultant told me sorry the router is faulty they need to replace it he gave a reference number for a bew router so we went back to cresta telkom, and the manager MARIO at the store was super rude and unprofessional it ended up in a screaming match between my husband and mario the manager and my husband asked him if he would be happy if something is still under warranty and you come home and they fixed it with sellotape he said no he won't so why must i as your customer be happy with it, mario said well he is the manager but he doesn't know how these type of things work so he goes on what the technician says in his store, a quick question how can someone on the floor knows more than your manager??? And he said in the screaming match that if he was in this situation he would've cancelled his contract so that was his solution. eventually we left @ 5:50 pm went to dion wired and bought an new router it was R1299, Because you know your store has a problem if people at your call center say they are rude and unprofessional and i should report it to hello peter, and that they have so many issues with cresta telkom.
