Disgusted in the service

I sent my TV in for repairs on the 1st July they told me it will take about 21 working days to fix the TV. I called them numerous times after the 21 days they just say they will call me back as they waiting on feedback from the repairs. Be in mind I have extended warranty on the TV. The beginning of August I decide to call them again they tell me they will call me but I couldn't wait then I would call them back. Eventually after numerous calls and weeks they told me I need to make a payment of R350 cause apparently it didn't cover now I'm liable to pay.. I decided to call the branch to find out how I can pay she says I need to come into the branch however I explained to her I'm far from the store I can't travel up and down as it cost money. I decided to go into another kenilworth centre where the lady told me I can make a eft payment she will give me contact details cause I can't make payment to there store only the one I did the warranty pr purchase etc. I called the people the next day with the number I was provided they told me my TV is not there. I called N1 city again last week to tell them then I was referred to different people where they said they can't give me the bank details I need to speak to Giovanni he will give it. I called Giovanni on Friday 1st September he told me he will call me back in a hour it's the 4 September I decided to call back he said he will return my call or send me the details until now still nothing I had to call back again back and forth. I'm done with game they won't ever get any purchase from me again. There customer service is useless.
