Refund dispute

I am writing this complaint in how *********** are your people. I bought a fridge at Menlyn Branch and finished it off at Centurion Mall. I mistakenly paid extra R125 on my instalment and i went to fetch my fridge there myself after too many attempts to collect it and i have made Musa or Muzi aware that i have credit that i needed to get back. Up to date i have waited for them to call me. I know its little money however it belongs to me. I am tired of waiting for that refund its been 3 months already. Please do what is right and pay what is due to me. Tymebank bank account *** Ndileka Kula Branch Code 678910 My number is ***, Ndileka Kula by name ***. Looking forward to hearing from you soon. Thank you
