Vodacom repairs, unsatisfactory service

I have now done my research and see that I am not the 9nly person who has received this terrible service from Vodacom, all I can say is that they are cheating people out of their hard earned money. I have booked my cellphone in for the 3rd time for repairs and everytime I said why can't I get a new phone seeing that the phone is faulty, it's not my fault, the first repair was logged 3weeks after getting the phone, the charging port was faulty, they say it was fixed 3 months later the same thing, and now 2 months later and it's booked in for the 3rd time. I got told every time 5-7 working days in total everytime is 3 weeks, I'm fed up, I need a phone, I'm paying my contract and have paid it everytime yhe phone was booked in, with no compensation or empathy for the situation, apparently the consultant in Kenilworth store cannot log complaints and I was told to contact Colleen Wilson, who's name is all over Google for bad service and she she is part of Customer relations, i have also seemed legal advice and according to a Cape Town lawyer, as per the Consumer Protection Act, I should have the choice of my goods/services being repaired,replaced or refunded. I'm truly hoping that some one can assist me by actually assisting me and not giving me stories that nothing can be done. I would like to escalate this matter and hoping that there will be a response to this because this is now how far it has come that a consultant or manager cannot assist.
