Bull Service

I bought Samsung zflip and Fold...few months after the Zlip had liquid due to opening and closing. Bought very hard and quality cover for it to protect it as I loved it so much...but guess what one morning I open the phone to stop an alarm and find that is black. Took it back to telkom and they send it back claiming I had dropped. My phone never ever fell, and I ask that the matter be escalated to senior tech and it never happened and they I must pay R8k. I have tried another branch and they returned me they said they can't fix it...m now sitting with it no one want to help...what's painful is my monthly payment...and I know few ppl who had similar problem with same phone but with different service providers and they have been assisted as they picked up is manufacturing fault but no at telkom shem...I have more than 10 years being a loyal customer to them but no anymore
