Bad service

Hi I visited NWJ menlyn to buy a ring I saw online I didn’t find it in store they called Brooklyn to find out if Brooklyn has it and they found out that they have it but didn’t confirm the price on the phone with Brooklyn however cashier at menlyn said the price you saw online is the price you will pay and we checked the size at menlyn before booking it with Brooklyn which it was T and I fitted it at store menlyn it was fitting just fine and I went to Brooklyn the following day when I got there the price was different to the price online 35% in store and 60% online they told me why they differ and I decided to order online which I again fitted the size which was T at Brooklyn then after I ordered online the same size which it was delivered within 2 days but the same size T is not fitting well compared to the sizing I was confirming at 2 shops now today I went to NWJ menlyn for resizing they are going to charge me R280 when I collect it on Wednesday
