A joked from ESH.
Yesterday they delieved the aircons to me and together with the 2HP unit as well, and I asked the lori driver
Jo: Is this for me as well?
Drive: Yes
Jo: Is not your company said didn't have it? As I already told the saleman and he confirmed didn't have. Why you get it from?
Drive: Maybe someone delay the deliver day, hence they just take and give you, but since you didn't want, let me call the saleman...
Jo: ....
After 10 min while they unload and bring rest of items to me house, so I just call the sale personal
Jo: xxxx How come they delivered the 2HP? Is not you indicated didn't have and will do the refund? Now how? As I already have a unit with me now
Sale: Hmmm..I'm not sure, but you really didnt want it?
Jo: Yes, I didn't want it as your end already confirmed didn't have yet after i get and you delieved it...
Sale: you really didnt want it?
Jo: Yes, I didn't want
Sale: OK...I will ask the driver send back.
Jo: OK, when will I get my refund...
Sale: Next few days...
Jo: OK...make sure. Else I will complain to HQ...
