online booking page faulty

Yesterday I logged on to check on availability and rates-last night decided when and where<br> this morning loggend on -website freezes I HAVE NO OPTION I MUST DEPART FROM ZANZIBAR 0N 16 AUG N O O T H E R C H O I C E!! I TRIED TO CALL THEM WAS CUT OF ON EVERY CAL 3TIMES. THEN SPOKE TO A LADY WHO GOT VERY IRRITATED WITH ME. I WANT TO KNOW WHAT THE PROBLEM IS THAT THE WEBSITE IS FREEZING SHE CANNOT ACCEPT I NEED TO CHECK RATES ON EVERY FLIGHT DAILY AND THE RATE SAID I MUST HOLD ON. OI HAVE SPEND MY TOTAL DATA BUNDLE FROM 8.00 TO 833 AND THEN TRIED TO CALL AND I CANNOT HOLD THE LINE TILL WHENEVER SHE GET BACK TO ME-JUST PUT ME ON HOLD AND JUST FORGOT ABOUNT ME AFTER ANOTHER 5 MIBNUTES I LOGGED OFF. THIS BOOKING ETIQUETTE IS N O T A C C E P T A B L E. THIS IS NOT THE WAY MANGO OPERATES.!!!
