The problem never ends. Up to now, I payed 270 euros to end the contract, but it is still charging me!!!!!!!!!!! !!!!!!!!!!!!!!!

I have not used the card for more than one month!!!!!!!!!!!!!!!!!!! And the mail was sent more 45 days ago!!!!!!!!!!!!!!!!!!!!!!!!!!

The money is confirmed by your staff!!!!!!!!!!!!!!!!!!!

You are still asking money from me, What is wrong with your company?????
If the contract is finished, stop sending me spam and give me proof of termination! ! ! !

If not, give me reason!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Stupid compnay and non-responsible service!!!!!!!!!!!!!!!!!!!!!
