Lancekart — After sales service and prices too high

Hi,

The prices of Lance frames and glasses are very high. The after sales service is not good. The after sales service is being avoided. The executive says to get the number of glasses from the doctor. So, which executive of Lancekart is checking the machine? If they are not giving the correct number then why is Lancekart keeping the executives. Keep experienced executives who can give the correct number of glasses.
I tell you do not buy Lance from Lancekart.
Thanks
