Dear sir,
Please there is not a problem , They will call you that is not a
problem or seem the want you call back , and this call is important at
all , do not think that they will just decide to take plane to come
here , they need more information to proceed this cleaning , so if you
are willing to process you need to discuss with them and note that , i
am just a business manager , i am not a technician , so all other
details shall be discuss with him because he will be in charge of this
cleaning process.
So everything is important for us to prepare everything and try to
work with you at best.
