Newspapers continually not being delivered

Our company, Allcare, took out an annual subscription to Mail & Guardian late last year. We have regretted this ever since. The delivery of newspapers has been most erratic and inconsistent.

And when we call the call centre, the standard response usually is that they will \look into it". However"
