Booking.com and Faircity Grosvenor Pretoria

Good day

I'm am really upset and if this matter isn't resolved i will expresss myself, i booked a accommodation for the 3RD May 2019, at Faircity Grosvenor Pretoria via booking. Com. it showed that well my credit card is declined i tried a couple of times it still refuses and notified me if i don't make a correction in 24hours it wont reserve my spot, i had to call a buddy of mine because i couldn't process this payment he then tried on his side aswell and couple hours later it showed the same message, i was shocked because this isn't the first time I'm booking from this site, seen all of this occured i decided to call Faircity Grosvenor myself i spoke to a gentleman to confirm is it possible to pay the price as per booking. Com of 1109 he said no that is a discount and they actual price is different should i book directly, i asked that someone call me as he couldn't reserve the spot he said someone would contact me back until today no one has called me back i have decided to go with another accommodation and here booking.com and Faircity is sending me a message enjoy your stay for the 3rd Guys what service delivery is this first you declined my card then another card thereafter you threaten to cancel my accommodation, which i get is fair, however i wanted to pay for it at first, booking. Com didn't allow me to, your staff couldn't call us back , Faircity Grosvenor Pretoria, and here you ready to give us accommodation and wanna take our money, well here's the thing guys im not paying a cent for this poor service delivery please rectify this error I'll be not using booking. Com again and take my business elsewhere neither this Chain of hotels should i get this kind of service or be charge for this situation.
