Im reading all the comments and dont think we are getting to the heart of this. Whether CS is good or bad doesnt depend on the product or company but who the customer is, who the staff is and what the customer is trying to get CS to do for them.
Generally speaking, CS is very inconsistent. Companies large and small never had training in CS and simply handle problems how they choose to as the problems come up. Everyone in Malaysia is more interested in selling than in service which pays little or nothing. So, they are very good at imposing limits on what they can and cant do, regardless of their true capability. When it comes to something non-paying, they will lean on saying NO.
Expats have an idea that CS is uniform around the world, particularly in chains and its not true. They think they can ask or demand anything and like magic it should be taken care of but even those people with a big historical spending record dont fare any better than someone who bought one cheap thing. Are you a VIP? Are you providing some kind of demonstration of future good fortune for the company and they want to court you as a customer? Are you asking for something small and reasonable? In my history, the best CS came at the time of a sale and never after. "I'll buy these things from you right now but I need these problems solved." Then you see all sorts of excellent CS. As a phone company repairman told me last week, "I service people who spend 10X what you do for internet and they have the same crappy service and net."
CS is also more dependent on the individual being asked than on the culture of the company. Ive had amazingly good and amazingly bad service in the very same companies depending on who happened to be helping at the moment. Ive had people tell me NO NO NO and then you contact again, get someone else and they go all out for you, beyond their duty. This shouldnt be a luck thing, it goes to the lack of consistent and uniform CS training which is absent here. And its really no better in the chains, too. I dont like fast food but McD or Subway service in Malaysia is not the same as in the US or likely anywhere else.
Actually, the only thing consistent about CS here is that the companies really dont want to give it. Here is something I have been told more than once while here. The conversation goes like this: "ok, you bought that thing from us, nobody forced you, it was your choice and that should have closed the transaction. Now you are asking for help on a problem which is a cost item to us and we can choose what level of cost WE are willing to endure."
Also, youd think a big brand means good service. Maybe not. I have mixed reviews on brands. My advice. Generally, buy as a one-way ticket, buy on the assumption you will never get CS later so that means buying carefully whether a service or product. If you do need CS later, stay nice and keep the request as small as you can. And keep in mind that the best CS will happen before a sale, not after.
