Pathetic customer service

I recently app**** for a fiber line in my area.I got super fast feed back from telkom when i requested a new product.So all seemed well they called informed me the area is still without fiber,i had no issue with that.So i asked them how much would it cost to increase my current 10MB line to a 20MB line.So the sales consultant informed me on what the extra costs would be i agreed and told them to upgrade my line.I asked how long it would take to upgrade she informed me 24/48HRS i said perfect.I am now on day 4 and still nothing has happened and they have already added is to my current bill at pro rata.Which i feel is unfair as i do not have the upgrade as yet.I am sick and tired of telkom robbing people and taking there own sweet time in doing there work.

And now i try go in store and they say all the do is sales and i need to phone in so flipping irritating.So i do that and wait on the phone for 20mins plus wasting my minutes so i hanged up.Trying to get them to call you back cause you have a issue never happens but if you wanted a new product you can expect a call in a few mins just shows where there priorities are not with existing customers.

So now i am in the dark on what to do cause i and so over this.
