Guys and girls, stop putting up with this bull shit, the solution is very simple.
Document everything, stop this useless phone calls that rarely get anywhere. EMAIL, keep it documented.
Use a credit card, unlike with debit, credit card gives you a protection. But if you have a good bank, and you are not flagged as a shit bag in their system, they will take care of you regardless.
Use pay pal, their service is good. If paypal starts acting up, get in touch with the bank and flag transaction as unauthorized, and paypal will stop their stupid games up real quick.
I use Amazon as an example very often. If there is even an issue, it gets resolved with few clicks and very minimal inconvenience for me. Why would i ever bother with anyone else and their "fuck you in the ass" costumer service, when there are better ways to do it.
There is an easy way to do things, and there is a hard way. Additionally some ways yield results, and some not. If you have a fetish for difficult and unproductive things, more power to you.
