My Samsung Galaxy Note 20 Ultra G5 displayed a black screen. Despite trying online and video repairs, none worked. I purchased a refurbished Galaxy Note 20 phone, but I needed a replacement SIM card. I contacted Virgin Media customer service, but the representative's foreign accent made communication difficult. The Virgin representative transferred me to O2 Services without any further explanation. However, the O2 customer service representative also had a strong foreign dialect as well, spoke too quickly, and unclearly without any good English diction or clarity. Also, they attempted to sell me additional services I did not require, leaving me feeling stressed and dissatisfied, and I'm still not connected to any network to any mobile link. I would not recommend either Virgin Media or O2 based on my unfortunate experience.
