Poor customer service

My mother made a payment of R247 on the 2/06/2022. She was called by the debt collector the following week. The payment is not reflecting on their system and they have been sending her from pillar to post with no assistance. My mom is 67 years old and she's been so stressing about this payment. The customer service from Mr price contact centre is so poor, they placed me on hold for more than 5 minutes until I dropped the call. I wish she listened to me when I told her not to open Mr price account. I've had a bad service from the store myself and stopped shopping at the store. Anyone considering to open an account at Mr Price my advise will be, not to open it or she will regret it.
