Thats my worry. This girl wants you to put 20 euro credit on to her telephone, and then she says you can deduct the 20 euro when paying her .... 100 euro for 30 mins or 200 euro for one hour....What happens if she turns off her phone or doesnt answer it or the mail box is full, or there is bad reception or her battery goes flat or you put it into the wrong phone,or she texts you and says all is ok?
Well thats the first question. Then you need a calculator to work out how much more to pay.
I have checked it out
80 euro for 30 mins, or 180 euro for 60 minutes.....So that makes it very expensive to go for an hour, 100 eros extra,I think
You would need to book 30 mins for 80 euro; and then another 30 mins for 80 euro, and lo and behold, you have saved yourself 20 euro.
I have a PhD in advanced mathematics, trust me
