Specsavers ridiculous Quotation

I purchased Multifocals from Spec Savers for R5300. I was told that it would take 2 to 3 weeks to get use to it by the optometrist and the gentleman that did the fitting. I tried it but the field of vision for reading to too narrow,the edges are out of focus. This causes me to experience motion sickness while reading. So I went back to Spec Savers The mall of the South. And was told that I need a more expensive lens. I received a quote from them for R11 234 less want I paid already which is 4381.60. Total to be paid now by me R6852.40

****************. I want a full refund of what I paid and I will go elsewhere.
