Total incompetence in trying to upgrade

Since the 1st May 2024 I have been trying to upgrade my contract with the Hillcrest branch. They eventually send basically illegible scans to me to sign. I made it known and wrote as such on my return scans. After a good 3 weeks the manager refused to upgrade and renew. I was never informed until I again made contact a week later. Excuse, manger was unable to read the scans. I was then told to phone him. When I suggested he phone me I was told he is very busy. A few days later a lady from the same branch called to do an upgrade with promises to sort the matter out. I was told on a few occasions to come into the office and explained it was a good 5hr round trip. Fell on deaf ears They are completely useless I have to say.
