The service i recieved for the last 2 weeks is pathetic

Since my upgrade on the 7th of september my phone has been blocked...Between the shop and costumer care I've been running in circles... Theres been no asistance from any management and everyone has been sending me to the next my phone is not suppose to be locked some kind of credit limit bar and no one can remove it.... so a service request has been logged on the 12 and it still hasnt been attended to so at this stage they say phone this number and then tose people say phone the next deparment and so it continues
