LACK OF SERVICE

I ordered a mobile wifi router from MTN online approx. 2 weeks ago. it finally arrived last Thursday 21 May. It wasn't working. I called MTN customer service they told me the sim wasn't registered, so the agent did that for me and told me to wait 24 hrs. more than 24 hrs later it still wasn't working, I call again and this time I'm told its not RICA'd and I should wait 3hrs for the RICA process to go through. 3 hours later its still not working. skip to Monday 25 May I call again and I'm told the email was sent to the relevant person by the name "Cindy Mhlongo" but there was no response. this agent I was speaking to said he would forward another email for a RICA request and to also express my dissatisfaction. 4 hrs later the device IS STILL not working!!!!. I call YET AGAIN to enquire and I'm told the 2 emails were sent but it appears this Cindy Mhlongo ha not yet attended to them and I was advised to go to an MTN store near me. I did unfortunately this particular store was closed. I even emailed the MTN customer care but I didn't receive a response. I converted to MTN thinking they have better service turns out its way worse. How can it take over 4 days to do a job that takes less than 5minutes ????? why must I use my petrol and time to do someones job FOR them? will I be compensated for this??? then what was the point of me buying this device online if I'm told to go to my nearest MTN store?? I could've done that in the first place and possibly avoided all of this. ice highly disappointed with the service received and at this point I feel MTN took my money and personal details for nothing which makes me feel unsafe at this point if this is how they behave. please come and collect your device and sim and return my money.
