Very BAD service

I requested a Sim swap on the 26 July 2019 at 14:40. I gave them the number appearing at the back of my new Sim card as per their request. I was told it will take 24hours to register my new Sim card. I made a follow up call on Saturday but was told I should wait as it takes 24-48 hours excluding weekends. On the 29 July 2019 I called again as the 48 hours has lapsed. I was told to wait another 24hours and then switch on my phone. Again I did that but still nothing happened. I called them again and was told to wait another2 hours but even now i still haven't had any help. In total i have waited for 80 hours plus. This is so unfair and un called for. This is pure bad servise and no value for money. My cellphone no. that I requested a Sim is ***. You can contact me at ***
