I faced the same problem and was charged nearly RM200 last few months. Made a call to complain but was told they cant do anything on it. This is not the first time I was unreasonably charged by Hotlink. Here I share another few times.

The first time, I did't realize my number was deactivated because they allowed me to top up through maybank2u, my money was well-deducted, but the money did not go into my account. In the end, when I couldn't call out, I realize my number was deactivated and circulated in the market. I spent a few hundreds to buy the number back and sign up maxis prepaid plan. They told me I couldn't get the "top-up" money refund to me. This is my first experience being robbed.

Second experience being robbed, when I traveled to oversea, I bought the voice pass but in the end I couldn't use it. When I called the customer service, I was told the service was not available in the area I traveled to. Why charged me and sold me the pass if the service was not available? The system should be improved to make sure you can deliver the service before taking customer's money. I was then asked to go back to the service center to get refund. Since the petrol and car park is more than the pass itself, I got to accept the forced-donation.

I have been staying with Hotlink for more than 12 years, but this is what I get in return for being a loyal customer. I am really disappointed and am planning to switch to other network.
