Awful refund experience

Im extremely upset with the bad service I have received from webafricas. I have signed up for fibre the beginning of May . The technician came out and was unable to install I then requested for refund which an agent on their end did not capture correctly. I then enquired again and provided banking details for refund to be paid and was advised to wait 10-15 work days. I messaged them again and was advised they will have it sorted within the next 24-48 hours. Today it's 22days that I'm still awaiting on my refund and still being told I have to wait 24-48hours when ever I message them. I find it really unfair having to run after my money and getting no assistance. No one within the business seems to be helping. I just keep being given a timeframe which they don't adhere to. I've asked to speak to management but even that is impossible. Agent are so unprofessional and has no way of speaking to customers. Disgraceful
