Telkom worst service ever

I've had no joy from Telkom I had taken out a contract via the online portal which was delivered within two days I had no hassles taking the contract but I have very poor coverage I had called the call center and was advised to take the device to the store and they will cancel the contract whice I have a voice recording of when I went to the store the Manger told me he can open a case and it will be resolved within 3 to 5 days I never even get a call for feedback it's been more than 2 weeks now and still no contact from telkom I don't find it fair as I will be debited again for something I'm not even using the router it's packed away and if this is the poor after sale customer service I don't wanna even look at telkom again cause I don't find it fair for me has a client and what makes it worst is the attitudes I get when I call in the call center to follow up
