Lack of service from Webafrica

I have payed a deposit of R399 on the 18 September 2020 for home fibre connection to webafrica with no follow up from them as to when installation will take place, yet they deducted another amount of R341 on 1st December 2020 without any service rendered.I have followed every alternative communication to them without any success.They have all my details and address.I even received a logon and password from them.In November I cancelled but no refund took place. Please help.Thanks
