bad service at Sleepmasters Wynberg, the service is pathetic

i bought a bed from sleepmasters Wynberg on Thursday 23 June 2022, bed was delivered same day, the sales person Lena advised that the driver works for them but i have to pay cash to him. on sunday 26 June 2022 we heard a loud sound from the base. we checked the base only to find out that it where the bed leg is put is loose and inside the base is broken. we called the customer care to report what happened and they told us that on their system it does not show that we paid for delivery in that case the store that we bought from will be able to assist us. we called the store and we told them that we want an exchange of the bed and rather upgrade as it seems this bed will give us problems, they insisted in fixing the base and we told them that we are still within our rights to get an exchange as we are still within 7 days of purchasing the bed. i have been calling the store and customer care with no help at all and at this moment i am fustrated as not even one of the managers are able to assist us. we have a broken bed that we can't even sleep on and yet we are not even getting any help. this is the worse service i have ever got. the store manager Nokhuthula is very rude and does not even want to hear anything we have to say nor give us any assistance. at this moment we just want a refund as i am just tired of going back and fourth with the store manager and call centre.
