Congested dates when plotting time series

I am having some issues when plotting my data with the dates being plotted to closely together making my graph difficult to read.

I have provided a small sample of the data set I am using below in the data frame count_date1, with the full data set the problem is even more apparent.

Date <- c('13-05-2015', '13-05-2015', '14-05-2015', '4/1/2015', '4/10/15')
freq <- c(24,12,23,18,21)

count_date1 <- data.frame(Date, freq)

str(count_date1)
#> 'data.frame':    5 obs. of  2 variables:
#>  $ Date: chr  "13-05-2015" "13-05-2015" "14-05-2015" "4/1/2015" ...
#>  $ freq: num  24 12 23 18 21

library(ggplot2)

ggplot(count_date1, aes(Date,freq)) +
  geom_point() +
  geom_line(aes(group=Date)) +
  xlab("Date") +
  ylab("No. of Complaints")
