I am very disappointed with Ackermans

I am very disappointed with ackermans. I bought a Sumsung A2 at Strand Ackemans on the 02-12-2020 and on the 09-12-2020 the speaker was not working well. When I brought it back they said they can not refund me or exchange the phone. So now I am waiting for it to be fixed for four weeks. I am living without a phone now as if it was my fault. What is the meaning of this:Refunds: • All products must be returned in the original packaging, and with all original accessories. • The product will be assessed by an authorized repair centre before any refund will be processed. This can take between 7 – 21 working days excluding courier times. Exceptions/ exclusions to the General Rules
