Full House Atlantis extremely poor service!

I purchased a fridge , tv and cellphone from Fullhouse on account a little over two months ago. This was done at the Full house Atlantis branch. The salesperson was eager to assist in opening the account and securing the sale. I went into the shop and signed documents and approved the debit order mandates. It all went downhill from there. We never received any information regarding delivery of the units , until we enquired. No after sale service was provided. After numerous enquiries we received delivery of the tv and cellphone. We were told the fridge will be collected from a warehouse and delivered the next week. The following week nothing was delivered or said regarding the fridge delivery. Only upon enquiring on the fridge were we told that the unit is not in stock and it will be requested from a different warehouse and delivered the following week. The following week came and went and no delivery , again upon enquiring were we told they have no stock and are trying to source a demo unit from one of the stores...After 3 weeks and a lot of enquiring did we eventually receive the unit. 3 Weeks ago the phone started malfunctioning , not being able to touch. We then took the phone to the store for repair, they advised that they will send it to the manufacturer. A week later my husband enquired on the status of the phone where he was told to please just wait as it takes 21 days. He then received a sms from Vodacom that he may collect the phone on Friday , this past Saturday we collected the phone and it did the same thing. The person at Vodacom advised he must go back to the store as they repaired it but it was clearly still not working. When he went to the store the stock controller proceeded to attempt to convince him that he must just press a few more times when the phones touch does not respond. I have paid 2 payments towards the phone and have 10 payments left , there is no way that I am going to pay for a defective phone. My husband left the phone at the shop and has now directly made contact with Vodacom and Samsung regarding this, as no one at the shop is interested in assisting with this issue. I have made contact with the Sales person who has advised that they can not do anything and I am welcome to come to the shop to speak to the manager. This is extreme poor service , no assistance , no after sales service at all ! I will never step foot into that shop again!
