Refused to change my password

I sended an whatsapp asking for the change of my password as I once did cause the is device that is supposed not be there, to cut the long story short the pathetic service I got is shameless, secondly I was asked to pay up 100 cause they can't do it manually, while I am shocked since when they ignored me, never bother to get back at me, ikeja is becoming pathetic and shameless what kind of nonsense is this,, I am shopping around for for better service. Whoever is running your what's app is rude and pathetic.. I am so dissapointed and bye
