Worst service of any company in SA- even ****** Eskom!!

I am absolutely appalled at the level of service received from TudorTech. They have had my vacuum cleaner for service and repairs for over three months. When they told me it needed a new part I paid over R2000 (over a month ago) and since just been waiting….. absolutely no communication unless I call them. Which I am having to do daily now just to find out what is happening. The worst service I have EVER experienced. And even now- they have no idea when the part is scheduled to arrive…. But in the meantime they are happily holding onto my money and my vacuum cleaner. This can’t be legal?
