Mtn momo bundles and mtn bundles don't work

MTN MOMO BUNDLES ARE A **** I have bought the R15 3 day bundle for months and now the last two weeks only part of the bundle that works is what's app. Try and contact mtn and nothing. Mtns other new trick is the 30 day voice bundles magically disappear I used 28minutes of the bundle on day 1 come day 2 I used R20 of my airtime because my 45minute bundle was gone.

So mtn contact me because I've tried to contact you you and sort this out via 135 and nothing so next step will be via tik tok Facebook and maybe a even a billboard telling the world how you rob people
