Unsatisfactory service from Billing Departments

Multichoice im so disappointed with the service that i have received from your billing department. After countless calls and emails my query has not yet been resolved.i was billed R893.00 for November 2018 and i pay R495 for Dstv Compact plus Xtraview.ive paid the R893 and now your billing Department says that i they have only received R495 and yet again i i was billed R193 for December,paid that and im still in arrears by R699 after calling the customer center the bill was reduced to R301 but still the amount that i have paid during December covers 2 months subscription with a change that was supposed to be credited into my account.ive asked your billing department to investigate this matter and the have not yet came back to me and ive received an sms that my services will be suspended if i dont pay R495 by end of business today.how can 1 person be billed so amny different amounts?
