Vodafone Fails to Deliver New SIM Card

I've been a Vodafone customer for years, and when I called to request a replacement SIM card due to issues like poor connectivity and other glitches, they assured me they'd send one to my address. I gave them my current address, and they promised it would arrive within a week. However, ten days had passed with no sign of the new SIM card. Frustrated, I called Vodafone again, and this time they said they hadn't even dispatched it and couldn't send it now. I reminded them of our previous conversation, in which they had promised to send it. They said they'd look into it and get back to me, but I'm still waiting. My call reference number is 1-5215776694289, and I urgently need my SIM card. Phone: 553 *****53. - Halil K.
