Disgraceful service from Gianni

I have taking out a Extended warranty in mid April and was wrongfully informed and then decided to cancel the policy.I was told to call client services to cancel but then decided to keep the policy but take option 2 instead.I spoke to a guy named Gianni Talatala who assisted to sort this out and he mention that everything is sorted out and the premium will be dropped and will be debited on the 1st May 2024.On the 1st they debited the wrong amount.I sent an email requesting a call back and he did and said he his not sure why they debited plan 1.He said they will allocate the extra amount and June premium will be adjusted but once again the wrong premium was debited.He now makes excuses and say he his now sure why and that i changed the plan after the debit order.He his such a useless ****.I sent 2 emails requesting him to call me and he didnt.This is the worst company to deal with and they dont know how to respect their clients.I expect a full refund of my premiums which i have paid and he wasted my money and time.
