Dissatisfied Telkom Customers

I have received a call from rewards representing Telkom a few months ago regarding a WiFi router.I have agreed to a 20 gig day and 20 night package,however upon arrival I switched it ON and used it for that day ,however the next day I received a message notifying me it was 10 gig day and 10 gig night and It's priced more than what I was supposed to pay.I have immediately called them to inform them and was told they was out of stock hence they have sent the package that was next available.I advised them I dont want this package as that was not what I have agreed on.I have called numerous times. and even visited Telkom store.as they advised me they will be sending the courier to have it collected but up until today I still have it switched off at home but am getting debited and It's linked to my cellphone bill.I am paying for something I am not using.I have not even received any courtesy call or correspondence NOTHING!! to the consumers please be aware of calls from rewards call centre they decide on products they feel you should have with worst customers ever
