pathetic service and turnaround time

Its been 2 weeks of back and fourth calling a waste of time and getting the run around to change ownership. Promised calls not happening and being sent incorrect forms and then being told i cannot go into a store to sort out matter ill be put in a queue but it's been a week and no joy and no programmes. It is starting to frustrate me. Ive never complained about a company before and understand teething problems, but this service is seriously pathetic and also being asked for details which was sent 4 times its starting to grate me. Can someone please make contact
