Don't answer phone!!

<p> I have made a reservation for two chalets and was supposed to pay the deposit yesterday. Mercy was so kind to change the reservation to one chalet and I received the deposit letter at 16:15 - I tried to call Sanparks from then until 17:00 when they closed in order to pay via credit card. I could not pay online because for some unfathomable reason the client code under which I am registered online is different from the one on the resrvation? I tried to explain that in various emails which were not read carefully because I received very confusing replies this morning regarding online reservations I tried to make last night, which I deleted to wait and see what the reply would be this morning. I am NOT impressed with customer service!</p>
