Mistplay complaint: wont pay out

at first the app would not accept my location to be verified from them. all setting were on and correct. it took days to get back to me which they told me to look in faq. i told them it was not helpful and the problem is with them. they then explained to me like i was a 4yr old how to turn on location. i showed them a screen shot of problem and they said it could not be fixed on their end. i deleted data and reinstalled on 3 devices. after my location was accepted, i now get a message saying processing your order which switches between 3 messages. ‘were processing your order, this may take a while’ and ‘not quite ready, were still processing your order’ and ‘were still working on it, hold tight’. I have left it goin round and round for over 20mins now and still nothing. does not matter which giftcard or amount i try. they dont and wont pay me the £60 i rightfully earned which is a breech of contract for them. please help. im in desperate need of a new washer and really need that payout
