Extremely disappointed

In 2022 we bought a Restonic bed at Sleepmasters Vryheid.In 2024 Desember we went to the store to complain about the mattress sagging.They did inform us that due to December shutdown our complaint will only be investigated in January 2025. However they did logged the complaint.After a lot of back and forth messaging our claim was eventually approved at the end of May,but we had to pay a warranty fee of R2610, which we subsequently did and provided them with proof of payment on the 25th of June.At this stage we spoke to a representative of Restonic,on which they emailed us the necessary information, reference number and contact information to send proof of payment..At first the store asked me if I made the payment and I said yes.They rep**** by saying the new bed will be available in 7 to 10 days.After 2 weeks I enquired again, and they asked for proof of payment. I explained to them that I did everything correctly and that the proof of payment was send to Restonic directly. Out of desperation I emailed Restonic again, explaining my frustration. They asked me for my contact details because they wouldn't have access to emails for a few days. I am still waiting for a response. Its been 7 months since we started the process and it's been almost a month after we paid the extra warranty fee. I am extremely frustrated and disappointed with this whole process.
