Worst network and terrible customer service

My data contact eas ending 31 March and a sales consultant called me and sold me a new data package that came with a new wifi router. The router was delivered (28 March) , but it didn't seem to turn on. I then went to a Telkom store at La Lucia mall in Umhlanga, after a spending over 2 hours there with them telling me they can't help because is was telephone sale to the helpline telling me to go a local store for them to activate I finally got attend. Only to have the store manager tell me the router was faulty and gave me his email address to send him the delivery details and he will arrange for it to me picked up. I sent him two email with no response. Then I called the help line, only to find an *********** person who also struggles to get the router to work. He hang up on me and I expected someone to customer service to call but instead I keep getting sales calls to sell me more products, when this device is not operating probably.
