Continuing problems with online orders

Every time I order contact lenses online there is a problem. I have been ordering my contact lenses online (with a valid script) for two years now. Not once has SpecSavers successfully uploaded my script to make ordering the next time hassle free. The last time I placed an online order - and complained about the delay in loading my script - I was phoned by the customer service person responsible for online ordering and advised (promised???) that the script had definitely been uploaded on the system and that there would not be a delay when next I ordered online. Now, as I was placing my online order, again I have been advised that my script is not on the system. I assume, like all the other times, it will take more than a week to upload my script and then another week for delivery.

My script is with SPECSAVERS - I did my eye-test at SPECSAVERS in January. My understanding is that this means the script should still be valid. I only buy my contact lenses online from SPECSAVERS and after many orders - still the script is not uploaded.

Why have an online ordering system if you can't get the basics right???
