Disappointed customer

I purchased a bedset in 2017 that is giving me problems, laid a complaint with them and they referred me to the direct dealer (restonic) iv laid a claim with restonic and they have requested a purchase invoice (receipt) that I have lost. I have called House & home on the 8th and the sales lady told me that they don't have receipts for those years ago and she will ask the supervisor to contact me with more information. Which never happened. This morning I called the store again it's either the supervisor is busy my contact details are taken, to no use. I called again the store still the supervisor is not available

I am soo disappointed with the service as a customer... We furnish the store with information and details are typed on their system but when you request assistance they send you from pillar to post but they can contact you for marketing purposes
