stop selling, they do anything, they hide information.
They told me they were giving me a discount for 12 months. Unfortunately I move and I have to cancel.
They explained everything to me, except that if I did not have a 24-month stay, they would charge me the discount that had been applied to me.
Bad luck in trusting Diego, a vendor from the north, in a contract figure, but they are 20 sheets and I think it is something important, that they had not explained to me ...
