Bad Service - Spec-Savers: The Glen

In July 2015 I had bought a 4 month contact subscription. On the 13th of Oct 2015, I ordered a new 4 month subscription of contacts as my current contacts were to expire. Being distracted by completing my Btech degree, I approached Spec-Savers on the 5th of Dec 2015 to check whether my contacts had been delivered as I had received no communication about it from Spec-Savers. I waited a long while in the store only to be told that my contacts have been back ordered. The lady informed me that I would receive a call from Spec-Savers sometime next week to fetch the contacts. By the 11th of December 2015, I had received no calls from the company, thus I decided to visit the store again. A lady by the name of Patricia was there to whom I told my story to. She checked my folder to see if the contacts came in, only to find that they weren't even ordered. I informed her of how highly disappointed I am, to which she offered me a trial pair of contacts. I am extremely disgusted by the quality of service from the store which caused me a huge inconvenience. There is a huge lack of communication with clients which is highly disappointing. I will really rethink ever dealing with Spec-Savers again.
