Sub standard merchandise

We purchased a Tasha Lounge suite from your Meyerton store on the 28th April 2017. The suite was delivered and we had it fully Scotch guarded and was very happy until 3 weeks ago when the seats started sagging and some of the wires started trying to protrude through the fabric. The pillows also were not as fluffed up as what they used to be. We duly contacted the store in Meyerton and they proceeded to arrange for the suite to be picked upon the 15th January 2018. Today is the 26th January and we still have not had an answer of what is happening. I have shopped at Lewis stores my whole life and I have never purchased such substandard merchandise as this. We do not want this set repaired it must either be exchanged for a new one or something to same value. We are totally aware of your seven day exchange policy but nobody could have foreseen that this was substandard merchandise. Could you please reply to me soonest or if you are not able to make this decision please escalate it to someone with that authority Hope to hear from you soon This mail was sent on the 26th January 2018 Next mail refers Our telephonic discussion refers. The Meyerton Lewis Store Manager as well as the Area Manager did an assessment on the lounge suite last week at our home. They both agreed that the workmanship on the lounge suite is below par so much so that when he felt on the suite where the protruding wires are he literally cut his finger open. My wife went to Lewis yesterday again and they agreed they will replace the said suite and gave her a brochure. There is nothing in the brochure that we like and that is why we request that our money be returned. This has been an ongoing saga since January as you can see in my mail below and there is still no conclusion. Attached is the invoice of our purchase Please reply soonest on your decision regarding payment This mail was sent on the 18th of March still no action apparently they cannot get someone to make a decision. I really hope some body could make a decision regarding this matter soonest
