Vodacoms no compensation

So I've been to vodacom at the Chatsworth brach over 50 times I would say to see if/ when my matter will be resolved. I'm starting to get tired on waiting for feedback from them because it's of no use. I took out a contract on the 14 April 2018 for the Huawei P20 lite the phone was faulty I returned it in the same week. I was not given a replacement phone nor was I compensated. Apparently if yiour phone is faulty within the first 7 days the company should replace it but not for me. I waited just over a month for a replacement phone and I was being charged for waiting for it. My debit orders were going out for a phone I never even had when I went back to their store the workers there should give me ****. I paid 2 months fees for a phone I did not have which is not fair on me and every time I call the vodacom customer care or go in store the only thing they say is a case has been opened. It's frustrating to keep on going to a store not to get anything in return. I want answers today otherwise I WILL stop paying my account. And I want My fuel my time that I had to drive after damn vodacom!!!
