Wasted time due to not knowing how to spell properly

I reported that I need a technician to come out to assess the problem with my fridge/freezer, phoned on Thursday 8 January 2026 and gave all the necessary details expecting some action. This morning I was informed that after spelling my email address, slowly repeatedly, and accurately, they still couldn't get it correct! What kind of education do the personnel that take these calls have that they are unable to spell an email address wrong, after spelling it phonetically and double checking each letter twice? Wasting valuable time and money! I think you should re-visit the training and guidance these staff members receive when joining your business as they are certainly not adding value at all.
