Mobile device cover and red cap foundation

I have phoned everyday since wednesday, 03 July 2024 to get to cancel the mobile device cover and red cap foundation foundation(which I didn't discuss with to be added into my agreement) and without success. I sent an email to *** and I was told for red cap I need to go to the shop and for insurance to send an email to *** which I did and till today no reply. I went to the shop and they also phoned and no one picked up for about 30 minutes and they did a call back. I thought they will cancel from the shop as I was told but nothing. I even sent an email to *** and no reply, as for online help where you fill in your details and what you ask help for is not working and keeps on giving an error. Now the statement has came through on the 8th and is still showing some balance due to red cap foundation and mobile device insurance. You call until your airtime ends. Can you please resolve this.
