VERY BAD SERVICE

I app**** for a top up contract 2 weeks ago with migration of my old number. I received my phone via RAM delivery services on Friday 27 October 2017 On 20 October 2017 my phone was connected. I notice that it is not on the top up option neither do I have my old Cellphone number. I phoned them to be notified that they do not deliver this service on weekends. I phoned again on Monday 28 October 2017 and was told that my contract is now fixed and is a top up contract. My numbers migration is also corrected and I can now use my old number. They then asked me what is the make of the phone that I got. I told them that it is a Galaxy Prime plus (for which I already bought a screen protector and a hard case for protection) Cell C said no this is the wrong phone and they will change it. I asked if the value is more or less the same and they said yes. I told them that in that case I will accept his phone as long as they confirm via e-mail that the value is more or less the same. Next day Ram deliver services knocked on my door to collect the phone. I handed it over and I received a sms from Cell C to say that the repairs has been done on the phone reference number CCD201398 I immediately phoned Cell C to ask what is the next step. Needless to say that I have spoken to numerous people that could not help me. I got an e-mail that said a cell c person will contact me within 24=48 hours. This was on the 1st of November. Ever since no one has contacted me, when I phone and give the reference numbers they tell me the relevant person is out on lunch I must phone back. I have paid upfront for my contract but is still without a phone, I do not know who else to speak to. I am desperate for help because I know if I cancel this contract now I will never get my money back as proven by Cell c, I cannot even get a phone out of them. Please assist me JE Appelgryn the reference number Cell c has given me on one account was ********** 860
