..Dear Sir or Madam,
I am one of your a customer of your supermarket. I am writing to complain about a minor accident that happened/occurred in the supermarket.
My first day at your supermarket was an awful one. [omit] Last Monday at 10 a.m I came there for to do some shopping. At that time the super market was partly crowded, so that it was not a good time for washing the floor specially with water and slippery substance, therefore everybody was gotten peeved for that as well. which was made very slippery. As a result Unfortunately, when I was shopping, accidentally [omit] I slipped on the wet floor and, what is worse, I broke my leg. I must complain about carelessly your worker.[omit]
In addition, Id like to suggest I suggest that your cleaners should do this work when the shop is closed, or that they should dry the floor as soon as they have washed it.
I trust these suggestions have been useful.
Please give this matter your immediate attention.
