VERY BAD CUSTOMER SERVICE AND CLIENT SERVICE ETHICS

I am so disappointed in the Service I have received from the online store I love and support the most! Purchased Remedy Health Slippers for my boyfriend (Size Large - According to sizing chart Shoe Size 9-10 at R499.00) When they arrived he could merely get his foot into the shoe, so for a start the sizing chart is horribly incorrect. I logged a return immediately and Takealot collected very fast. I could not find the exchange for larger size on the system and contacted their customer service just to be told that they cannot just exchange and send me a bigger shoe as there is a price difference. The large shoe at R499.00 and the X-Large Shoe at R399.00 (Less than bigger shoe - makes no sense) and that the same brand and shoe comes from two different suppliers. Large from one supplier and X-Large from another supplier??? Therefore I must wait for refund, purchase the right size and pay delivery for A SECOND time for the SAME pair of Slippers???? Which can take at least a week or two before this is done? Does this make any sense? Is this customer service and fair to your clients? In the essence you sell products at different prices for the same items depending on size and supplier and should it be to big or small, it cannot be exchanged? This is surely according to my knowledge not GOOD SERVICE or FAIR PRACTISE towards your clients. I will surely think twice before purchasing items from Takelaot again!!!
