dissatisfaction of Refund

I made a layby at Edgars on 26 September 2025 of R2000, on 26 October 2025 I went to release the phone but I couldn't the manager at the store(BLOEMFONTEIN Middestad) said there's a problem with my slip saying the codes don't match but he will contact IT people about the issue, I went again on 28 October 2025 to pay R700 because the problem was still not solved, so in total I paid R2700. This month on 18 November 2025 I went back asking for a refund they still did not help me they said they have to call IT people again they responded saying they can't help, then they escalated the issue to Reginal Manager of FREE STATE him too couldn't help it's been 2 months going to Bloemfontein Middestad Edgars about the same issue and I'm still not assisted.
