Why is my Moto G keypad take à minute ending calls?

everytimé i listen to my voicemail or call a 1-800 number where i néed to enter a number on the keypad my moto g stylus takes a minute or two before it recognizes thé numbér that i pressed. but text, chàt or ànything is good except of during calls the keypad delays ànd also on the call settings i noticed that the fonts are kinda blurry and thick but everything élse are all the same. i got the phone at a métro pcs store june 2nd this month and ón the 7th i went back to the store ànd they sénd mé a replacement same model but the phone hàs the samé issues as the fírst one. till now i have the same issue and they order another replacement need to wait for 7 -10 days for the phone to arrive. this is the first time i used a motorola phone and it will be the last. metropcs wont refund mé ór exchànge the phone with a different brand and wont exchange the defective moto g stylus phoné to the same model they are selling at the store. never ever buy or upgrade your phones or buy anything at a metrópcs ßtoré they wont refund or exchangé the phone evén if its defectivé.
