No contact after complain of intermittent throuput

I have contacted Telkom Mobile's head office on three occasions. <br> <br> We have been on the receiving end of intermittent throughput with our DATA. <br> <br> My ref number is ***4. I have also sent emails to your helpline, whereby they stated that I am to call the data department. However, I am hard pressed to find a reason as to why I should be the one that is to waste my money, yet again, to sort this out. This is your fault and should be sorted out at your expense. <br> <br> <br>
