Disgusting Service received at Kuils River branch

My name is Wakhile Lebetloane. I purchased a Res tonic bed at Best Electric on the 29-07-2014. With in 3 months, I called the store complaining that the bed was making noises(springs). Since then I have been accepting excuses from the store manager Ilza where she continuously **** to me informing me that the will send and investigator to look at the bed. It is now November 2015 and no investigator came instead, last week, Ilza made another false promise stating that the bed would be collected last friday the 20th before 17:00pm and this never happened. Saturday the 21st November, My wife and I called the store and they informed us and promised that they would collect and deliver before 11:00am. This was another lie as we had to waste more airtime in calling the branch. Ryland Prinslow read an email that I sent to him on the 9th of Oct 2015 requesting him to contact me however he never bothered. On Saturday the 21st Nov after being let down again I informed the store that I want them to take back everything and refund me so that I can purchase a bed elsewhere. My wife and I are sleeping on the floor and that bed is paid up already.The service is Pathetic, Please help
