Need urgent help

I Matthew Mosolo have encountered a problem with capitec,I want to change the number which is used on my capitec card,the number used us my mother's and it was used because I was under-age at the time so she opened a capitec account for me using her details but now I'm at a legal age(18) and I live in a different province compared to my mother so when I went to capitec they said my mother must avail herself and that request seems to be impossible considering the finances concerned that includes transport therefore I could not be assisted. Can any agent assist with the above matter as I need my bank statement urgent to verify my banking details with my sponsor so I can get my allowances
