*******, 25% fee to pay to get my Refund!?!?

on the 29th March 2018 i bought a Vega Mini stater pack by a Twisp counter at 3 Rivers mall. The lady that served me was very friendly but not so much knowledge of the products. after i got my Twisp i was using it in the mall no problems. as i got home all was still fine. +- 5 hours later the device started pulling out liquid by the mouth piece. after reading the booklet and also online VIA youtube as the Twisp web page does not help at all what to do so on youtube it showed me to clean it out ans.... then all was working again but only for +-30 mins!!!! i called the customer carre line number but no help. i left it as is till yesterday 03/04/18 to go back to the mall and see if the Twisp counter could help me. The Guy there told me that the device would do it sometimes? "i mean really????" its not small amounts that is coming out of the device but ALOT!!!! anyway the guy also cleaned it for me and used a new coil for me. i told him that i would be testing it in the mall while i was doing my shopping. Not long +- 20mins the device was doing the same again, i got back to the counter to ask them that i am not happy and would like my money back, long story short i had to pay a fee of 25% !?!?! so that would be the amount i paid - 25% of the total.... no fair at all as i was not aware of this and there is no boards arount showing this or nothing on the cash slip. i told the guy that i am not happy and that i am not going to pay for that. he called his manager "Niel" and had a chat to him. "Niel" said that it is the way, well well well did this push my blood pressure up!!!!! after telling "Niel" that my lawyer would be taking this from me then "Niel" said he would not ask me the 25% anymore but that i would had to wait till the Friday 13th April 2018 for a refund back into my bank account???? why not refund my money back to my bank card like you took it from the 1st place!!!!!! i am not happy at all and hope for "Niel" part that my money will be in.......
