Russells pietermaritzburg worst customer service

I Purchased a bed at the Russells at 418 Church street pietermaritzburg in September 2018.By December 2018 the mattress was sinking and became extremely uncomfortable.I phoned the store on the 2/01/19 and spoke to the manager and was told the supplier is closed and to call in the second week of January.I called on the 16th, 17th and 18th January 2019 spoke to the manager and was told a rep would call me back.My wife sent a customer complaint asking when would they contact us, it took 3 days for a response from customer services.I called the store 3 times on the 30th january 2019 and was told someone will call me back.My wife tried 5 times to call their head office and kept getting transferred.To date we have got no help or assistance from Russells.It has been over a month since the 1st call to Russells.This has been the worst customer service experience I have ever had and will never again make any purchases at Russells again as they treat their customers very poorly.
