Shocking service

I have had endless problems since the day I got this contract. I want to cancel but when I sent my email it bounced back. How am I suppose to get any help. This was my email below:<br> Good day<br> <br> I would like to cancel my mobi wifi. I have had endless problems from day 1.<br> <br> I waited far too long to actually get the product. I app**** and was told it would take about 48 hours for me to get a call to collect. It took over a week and at which time I had not received a call to tell me to fetch it. I went in and found out it had been ready for me for a while, but no one had called me.<br> <br> Then my incorrect account number was entered after I had given my bank statement. This happened twice. As a result I was charged bank fees and interest. I have cancelled the debit order. Due to the money not coming off I was cut off after being told I would not. Then after I was reconnected I am charged R578,07 for re-connection fees. <br> <br> When I went in over the weekend and I was asked 'What do you want me to do about it?'. Service all round has been shocking. <br> <br> With this package I received 2 SIM cards with minutes and data on. I have not been able to use this since I was cut off. I want to cancel with no fee.
