Capitec you have failed me

Capitec has done it again. I purchased R100 airtime using their app at 02:17am this morning but they only deducted my money from my account and never credited me with the airtime. This is the second incident to happen in less than 2 weeks. The last time it happened was on 04 Jul 2019. It is something that happens frequently and more than twice each year. I have reported this matter on numerous occasions and have sought a permanent or long-term solution but none was forthcoming. They don't take me seriously. This is a nightmare due to the fact that I use my laptop and data to complete my projects and now I'm stuck. They have just lost me as a client and I'd rather go back to my old bank FNB because I never had any problems there, I only moved to Capitec because they are cheaper. I guess you only get value for money, I'd rather pay more for a better service. I can only be patient for a certain amount of time and now I have reached my limit of patience.
