Macro need to do the following:
Look for the duplicate of phone number (etc. string at the end of cell A4,
A7,
A10... A10000) - where the phone number is in following formats:

031/xxx-xxx or
032/xxx-xxx or
033/xxx-xxx or
034/xxx-xxx or
035/xxx-xxx or
098/xxx-xxx or
098/xxxx-xxx or
098/xxx-xxxx or
091/xxx-xxxx or
091/xxxx-xxx

and delete the row with original and duplicate (etc. A10 and A16) - with one
row above and one row below.
