Cassh depost fee increase of 428 %

When checking our bank statements, I realised that standard bank increased our cash deposit fee for 2014 to 2015 with nearly 500 %.This is from r7.00 as per previous year to R30.00 per transaction on a society scheme accounts .There is no pricing guide for 2015 on the internet for said account ,and this is a total *******, Taking into account the many black stokvels and burial society ,which make use of this account ,this is a total *******.I submitted a complaint on to CRC in their website 7/5/2015-no response.A deposit of R50.00 cash cost me R30.00 cash deposit fee-ridiculous..Also waiting for feedback from the business banker w.r.t my complaint
