NOT GOOD SERVICE

About 3 months ago a bought a small lounge suit from Lewis store in Tzaneen. From the first day is was not completely satisfied with the product. However just before the 3 month period i decided to settle the outstanding balance. I asked the store manager if its possible to exchange the unit for another one, and pay the difference if there is any. I don't know why that guy is the store manager, really he is not helpful at all. On top of that, i specifically asked them, NOT to debit my account as i settle the account before the deduction date, not the went and debited the instalment. Please refund my money a.s.a.p. I will never buy from Lewis again.
