Personal approach of staff has made all the difference
I apologise for sounding grumpy in my previous review. Sky Tours has finally found a good solution in my case, and after exchanging a few emails, we have come to an amicable settlement. The company is going to fully refund the cost of my ticket and will charge only a fee of 19 GBP for their services , which is fair. Part of misunderstanding was possibly my fault. I have now gained more experience in booking flights on line. Many thanks to Elisabeth for her prompt reaction and flexibility.
