Vodacom Fibre a let down

Vodacom has proved themselves very devious with regards to their sales, management of customer contracts as well as fluid communication and follow up with their long standing customers. I was automatically migrated to a contract that increased my monthly debit for home Fibre from R529 to R829 without proof of email communication forewarning this, without any signature and then without any email communication as proof thereafter when requesting this information. I was then directed to the retention department when calling in and agreed then on a contract with debit R 551 monthly starting 1 June. Though this contract was signed electronically on 30 April, Vodacom persists to debit me R829 today. I am further then called in sporadic episodes from various Vodacom sales agents to move to 2 yearly contracts even though this electronic document was singed 30 April. There seems to be some serious misalignment in the sales and retentions department that requires an independent investigation by senior management. You risk losing your reputation as a leading brand and seriously need to up your game. Customer satisfaction and services delivery has fallen by the wayside with your brand.
