Incredible Connection - Festival mall - Bad service

I bought a volkano speaker on the 24th of October 2020. I took it back to the store 1st week of December as it was faulty. At the end of January my speaker was still not fixed - After numerous phone calls and store visits. On the 11th of February i went to the store because i was informed that the speaker is back and has been fixed. I quickly tested it and it sounded okay. On the 12th of February i played the speaker at home and discovered that its worse than before and its making noise while playing. I called the store again this morning and I was informed that they will need to fix the speaker at least three times before i can get a refund.
