Fixing a Blackberry on my own and saving RM75 charged earlier ...

I went to a shop  yesterday to fix my BB which had no ringing volume. The man at the phone shop  when asked about the cost of repairing the BB told me it would be RM75. I then said to him..."mahalnya", and he said " kalau nak murah , repair sendiri ya..." He was being very rude. I then went out and told my husband the cost of the repair.  ( I didn't tell him about the problem before). What he did was he switched the handset off and took out the battery and put it in again and switched it on again and walla!! It worked! I got back all the ringer tones and after putting the sound to normal again (I didn't realize it was silenced), the BB was back to normal. ... Here,  I have saved RM75 which was supposed to be the cost of repairing the BB.... What an experience...
