This happened with my car. The belt was new, but there were 2 other problems: the warning lamp cable needed replacing, and the belt's idler's mounting holes were oval. The latter necessitated a new idler.
Have the belt and associated bits and pieces checked. If the belt fails, then more wads of undervalued currency may need to venture forth from your wallet.
