Failed Return- Clicks not the same anymore

I purchased electric appliances online as they were on special. On my order I purchased 2 stove kettles without noticing they were stove kettles upon collection at the Gugulethu Store I was made aware by one of the consultants that the kettles were stove kettles and not electric, immediately I requested to make an exchange or get a refund and they told me that they do not sell those kettles(Kambrook Stove Kettles) in store therefore they can't take them as they won't be able to sell them. I was so puzzled by that as I thought all Clicks Stores are the same, I work and reside near Gugulethu Square hence I always collect my items there. I was then inconvenienced to go and return the kettles to another store. I then asked my husband on the 4th of September 2020 to return the kettles at Clicks Sanlam Centre as the Gugulethu Store gave me a number of stores that sells these kettles. When he arrived there the staff was so rude and were ignoring him the whole time, I had to google the store number and requested to speak to the manager, they dropped the call on me 3 times deliberately at some point I was also transferred to pharmacy while I made a clear indication that I need a manager. I ended up calling my husband and ask if he can ask for the manager there and ow! The store manager said if I want a refund I must email them the online invoice which I did on this email: *** which I did at 16h14pm however they kept on saying they have not recieved the email. Well I then spoke to the manager and she was no assistance at all and couldn't even advise my husband of what to do if he can't get a refund. I am so disappointed with the level of service I have recieved at both these clicks stores and I am a big Clicks Shopper as I collect my Chronic Medication with you guys, I buy all my baby stuff, toiletries and electronics by you guys and you do me like this. Now I am stuck with these 2 Stove Kettles and I don't know what to do with them.
