Inability to burn recovery discs on Acer Aspire AS3810TZ

I am unable to burn a recovery disc set for my Acer Aspire AS3810TZ laptop. The computer-held software programme burnt the first (disc 1) successfully, but it failed to complete the three-DVD series, repeatedly failing to start the disc 2 burn sequence. It repeatedly asked for a fresh DVD , thus wasting discs which cannot then be re-formatted.

I discontinued the attempt and started from scratch. The programme then refused to work even for the First disc sequence which had previously worked. After wasting 7 DVD blanks, I gave up.

I am at loss and could do with constructive assistance. Does Acer have a non-premium phone number in UK which I can use to ask for a recovery disc set with Windows 7 thereon, to be sent to me?
