Install all of google servies alcatel one touch fierce xl
root shouldn't delete the play store !

Did you do anything else ?

was it a dirty root zip 
( maybe ported from a new gapps installer as a base ?)
gapps is all i can tink of that would delete your store because it cleans up your old installation first, It sounds like someone made their own root.zip and used the script from gapps, thinking it'd just install root files into the system and not wipe anything...
