Stor-Age bad customer service

I entered into a self storage agreement with Stor-Age Somerset West at a monthly rental of R2069,09 per month in September 2024. After only six months into the agreement my monthly rental was increased with 15% to R2375,00 per month in April 2025. I queried with Stor-Age Somerset West due to the fact that the 15% increase is excessive and way beyond inflation and was implemented only six months after the agreement was signed, My query was referred to Stor-Age Senior management and after many requests they are just prepared to reduce the increase to 10% which is still excessive and still only six months after entering into the agreement. My impression is that Stor-Age offers favorable rates just to get the business and once you have signed the agreement, they cant wait to increase their rates far beyond inflation well knowing that it is not easy for their tenants to move their belongings due to cost and logistical implications.
