HORRIBLE CUSTOMER SERVICE!!!!

I bought my son a Tevo Shox Enduro drone, priced R1500 at Toys R Us Somerset West, for his birthday at the end of October last year. Upon payment I asked the cashier what I needed to do in the event of thee drone breaking. She told me I could just return it to the store, with the proof of purchase. In December, while on vacation, the drone stopped flying as it was unable to leave the ground. I promised my 8 year old son that I would have it fixed after the holidays. I then tried to purchase an extra pair of propellers, just in case this was the problem. I e-mailed ********** on 14/01 and to date have received no response. Then I decided to return it to the store in the hope that they can have it repaired. At Toys R Us Somerset West I was told that they would send it for repairs to Tevo and there might be a cost involved as the guarantee is only 3 months and I had just missed it. I was told that someone from Tevo would phone me in about a week's time to inform me what is wrong with the drone and inform me of any costs, if there are any. This happened about 7 weeks ago. After about three weeks I had heard nothing and so I phoned the store. I was told that they would follow up with Tevo. I again gave it a few weeks- nothing happened. On 11 March I took the initiative and emailed ********** - to date I have received no reply to that e-mail. I again emailed ********** attaching my previous e-mail, but to date I have received no reply either. I then phoned Toys R Us Somerset West again and I was informed that Tevo was meant to send me a quote.....Long story short....My child no longer has his drone. It has been in for repairs for about 7 weeks, and I still haven't received any feedback. How disappointing. I sincerely regret purchasing this drone. It is not only about the money...it is the disappointment I see in my child's eyes and not being able to give him any feedback. I made a poor purchase, but I can say I have learnt my lesson. Customer service at its worst!!
