Useless service. Line has been down for a week

I am utterly disgusted by the service you receive from Telkom! They have no regard for the clients and only care about new business. My line has been down for a week now and no one has contacted me! I’ve been messaging them and all I get told is someone will revert back shortly! I want to be credited for the data I have not used from them as well as the data I have had to purchase from vodacom! I want my query resolved this week or you will cancel my contract at no cost to me because this is unacceptable service (if you can even call it that)
