over paying

<p>I did an upgrade with Mweb over the phone about 3 months ago, they sent me a quote saying i will be paying R220 a month VAT INCL. i got billed R240 i followed it up and hey said they will investigated and revert back to me, instead they just email me my statment which i am able to see if i log into MWEB account page, i called again and same thisng, they just email me my statmnet and also they email you from an adress you cant reply back to, i log another call with the contract agreement and again they send me the statmnets and invoices.the statmnets and invoices dont explain whyi am been billed an additional R20 extra, i also thought maybe i over used my data and the consultants says NO but we will see why and get back to you, but again i get sent my invoices and i have been trying for 6 weeks to get an answear. today people dont appreciate loyal clients whom pay monthly for over 10 years and want a bit of service.</p>
