The most appalling customer service I have ever experienced - eBucks is literally putting my dad's life at risk through their sheer incompetence

My 76 year old dad loves technology. I bought him a new phone from eBucks for his birthday (to keep him busy and safe during lockdown). I presented his gift to him a week before lockdown, he switched it on and it had a green line of faulty pixels across the screen. I immediately tried to get it replaced with a working unit, yet >8 weeks and >20 emails and >10 calls later my dad still doesn't have the phone I bought for him. This has honestly been the worst customer service I have ever experienced. I am ashamed to have convinced my family to bank with FNB.
