Account incorrectly suspended for R2.33

I've been a customer for more than 20 years, my account paid by debit order without fail. On 14 July my internet service was suspended without warning for an amount of R2.33 (two rand 33 cents!) claimed to be overdue by Mweb. I paid it immediately and in the night, received a message that my my account was active but internet service was still not working. NO HELP over weekends so only on Monday was a VERY helpful technician able to restore service
