****** money whilst booking

On 22 May 2021 I booked Airlink fight online from East London to Johannesburg for 24 May 2021. My Trip (company name) was the one who attended to my booking. The time I was booking this ticket on line it was R527.00 and when I made the payment it went up to R1 041.00 of which that was not what I saw initially. I emailed them on the same day requesting for a refund, but there was no response. I phoned them on this number *** and I hold for a hour before my call was answered. Rajwinder who said he don`t have a surname attended to my call and told me that R1 041.00 was the price of the flight not R527.00. And that is a lie because the price changed immediately the time I was making payment on line, meaning that they are manipulating the system, ******** customers, robbing them. When I requested for a refund he told me that the penalty is R750.00 of which it is far above than the initial amount of the flight which I saw as R527.00. I requested to speak with the Manager. He put me on hold for almost 5 minutes and when he returned he told me that his Manager will come back to me within the next 3 business days. He never came back to me up to today. When I asked his Manager`s name and surname, he gave me the name only, Mahul and said his Manager does not have surname. I am very disappointed that Airlink can put us as customers at risk by linking our bookings with ******** who are greedy for money. Unfortunately, I deserve to be respected as a customer not to be taken for a ride as My Trip did. My Trip must refund me the difference they overcharged me with including all the inconvenience they put me through unnecessary. Email: ***
