Bad Product / No product training / No After Sales Service

In March I went to Lavana Beauty Spa in Benmore to purchase Nimue products that I had been using with good results. I was advised that they did not stock the range I was using but they could highly recommend another product with was better and I would see better results - the product was Lamelle. I purchased a moisturiser, eye cream and serum. As I still had some Nimue left I finished before starting to use the new products on the 30th March. I departed SA on 31 March on a business trip to Europe. On 1 April, my face started to feel itchy. On 2 April I woke up and my face had swollen to twice the size, was red and itchy. I immediately sought medical help and saw a Professor of Dermatology in Frankfurt who diagnosed an allergic reaction. He have me medication and said to stop using the products. On returning to SA on 13 April I believed the reaction was gone and started to use the Lamelle products again. On the 15th April I once had to go to my GP as I had the same reaction to the product. It felt like my skin was being burnt by a chemical. I was once again put on medication. On the 16th I went to Lavana with the products and all the invoices etc from the doctors and showed them photo's of my face and explained what had happened. They were sympathetic and 2 of the the******s picked up the serum and both thought that was the cause. They said they needed a few days to give me a response as they had to speak to the owner of the business and to the Lamelle representative and would have an answer for me before the end of the week. However no response. On the 6th May I received a call from the Spa Manager who said she could only give me an answer on Thurday Morning as Lamelle wanted to test the products. Thursday afternoon (9 May) I called them to find out what their decision was regarding a refund. I was advised that the other Manager was off and someone would call me back - I responded that they had to call back before 09h30 on Friday. Friday morning at 10h00 they called to say I had 3 options, a credit at the store, a voucher or a refund. I opted for the refund. I said I would come in after lunch on Friday so that they could refund the card I made the purchase on. I went in at 17h30 and was told that they could not refund my card but they wanted my bank details and would eft the money to me. I asked for a time frame and they said they would give my details to their owner. For a service industry company, the service is shocking, They are back tracking, making excuses. Apart from the cost of the products - I have medical expenses for R3500.00. Plus I don't know the long term damage to my skin. The strange thing is that the serum does not even print the ingredients on the product - so you have no idea of what is in it. AND Lamelle have made no attempt to contact me.
