Constant blocking of phone.

It has been the most annoying and frustrating process since Autopage took over the Nashua Mobile Cell C contract.<br> My Cellphone line gets blocked at the end of every single month, for the new month for reaching my call limit. How can you reach your call limit if I have not used my free 100 minutes and 100sms and I also use WIFI and no date?<br> I have changed my call limit to none, I have changed it to R2000 to no avail it keeps happening. I have a reference number, call centre agents promising me that they have solved this problem. Since the 1st of September I have phoned the call centre more than 10 times as I receive a message/email every night saying once again that my phone has been blocked.<br> I am at the end ..I no longer know what to do. The only option left for me seems to be to pay for the device, cancel my contract and go to another service provider. This will be at a huge inconvenience to me as that line won't be working for a few days...and it is used as a business line so I don't want to inconvenience my clients.<br> It does seem like it will be less of an inconvenience than having to deal with Autopage's incompetence every single month!!!<br> <br>
