Blocked sim card

I went to Telkom branch in eastgate mall to get a new data contract, after 3 hours i was helped and told that i have to email them my bank statement only thereafter will i get my stuff, and they will call me to come fetch them. On a Monday i emailed them the docs as requested. Two weeks past didn't hear anything from them. After these 2 weeks i decided to go to the branch again to enquire, when i got there i had to wait a further 3 hours again. I finally got my stuff, i asked for 2 sim cards so i can use the other one in my mobile wifi, they gave both sims which i was happy about after much frustration. Went home plugged my new toy, everything worked quite alright. Today tuesday the 18th November my wifi modem is not working i call to enquire about it and i am told that they have decided to block my sim card which has been working and i can only use the other sim card. And to add to my frustration to unblock this sim i have to go back to the branch and get it unblocked.. is this what they call a good service? I can't go back to that place again, and if this sim is not unblocked i am going to reverse the debit order when it comes through.<br> <br> Thanks.
