Decofurn Fourways ***** and Poor service and quality

I recently purchased a gaming office chair and paid over R2000 for this item. My first bad incident was the fact that the store had no stock and requested it from their warehouse and i was told i would be contacted when stock arrived. This was purchased on the 15th of January and i was only contacted on the 20th of January informing me of stock arriving, of which the staff member did not advise me to fetch the chair within 7 days and i got a call late afternoon on the 20th. On the 22nd of January i received an email from Decofurn stating i was contacted several times 9 days ago which is factually incorrect. Instead of apologising for their incorrect email, they apologised for the way i felt......but Decofurn fourways was at fault. Therefore taking no responsibility for their actions. I was only able to fetch the chair on the 28th of January and i informed that of this day when i wouldnt be working. I assembled the chair on the 30th of January and immediately noticed it was a defective item. I called the decofurn warehouse on the 31st informing them of the exact issues, this being uneven arm rests and further to this the backrest was uneven (one side was more forward than the other) and this actually hurt my back even more. I spoke to Thabang when i did call in to complain and they asked me to bring the chair back on the WEEKEND, of which he said they would be able to make an assessment at the warehouse. I was only able to take the chair in on the 5th of February which was a Sunday. When i arrived it took them a while to assess the issues and they further jerked my chair and backrest by trying to force it into position which actually damaged the chair further and we showed them the holes and damage created on the day. After waiting on them, they called in their assistant who advised that its passed the 7 day return period so we would need to write up an email to ***, after taking the time and wasting my petrol to drive all the way there, they did absolutely nothing to assist me. I took the time to draft the email and was assured it would be sent to head office who would be able to advise next steps and i would be cc'd in all communications, this was a lie because up until today i have asked for the emails and received no response from decofurn fourways. I have a defective chair which cannot be used and doesnt serve its purpose, i've been emailed by the assistant stating that taking into account my claim and the damaged part, they would only be responsible to change the backrest!!!!! After seeing what they did on the same day they now want me to bring in the chair again for the damage they have caused!!!! which could have been changed on the same day which i was there and they refuse to even deliver this, decofurn fourways has clearly stated that the damage is on their side, they have not forwarded me email communications and now ignore all my communications. They are ***** and provide poor quality products and services and have inadequate staff which cannot even advise their customers appropriately. I expect them to fully refund me or replace this chair entirely at their own cost.
